Answer 1

Vertical angles are opposite of each other when two lines cross. And corresponding lines are the side of each other when two lines cross

Question 2

Isoleoclles triangle vs equilateral triangle vs right triangle.

Answer 2

Isoleoclles triangle has two sides that are the same. equilateral triangl all sides are the same.

Question 3

How to solve right triangle using the outside. Ex x/2 and stuff. there is 2.

Answer 3

First one is 2 45 angle. And across 90 degree angle is x squared root 2. Hypotenuse is X and opposite is X. The second one is 30 degree angle and 60 degree. Adjacent is x hyportneute is 2x and opposite is x squared root 2. These can only work with special right triangles.

is the line or line segment that divides the angle into two equal parts

Question 11

Parallel vs perpendicular lines

Answer 11

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

Answer 12

180 (n-2)

Question 13

How to find exterior angle?

Answer 13

Sum of two angles

Question 14

PYTHAROGEN THOERM AND WHEN CAN T BE USED

Answer 14

he Pythagorean Theorem only works with right triangles. You can use the Pythagorean Theorem to find the length of the hypotenuse of a right triangle if you know the length of the triangle’s other two sides, called the legs

Question 15

What is radian and how to convert to angle

Answer 15

raidan to angle = raidan *180/ pie. angle to raidan. Angle * pie/180

Question 16

What are some ways to find missing side length. First for equilateral then right triangle then isoloeces triangle.

Answer 16

irst triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that you cannot draw a triangle that has side lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12. Also for isoleoces triangle. If you have 2 angles you know that the third one must add up to 180; For equilateral the third angle will equal to the other two. For right triangle you can use patherogrm thoerm. and unit conversion if they are conguent

Question 17

How to know if it will be a special right triangle

Answer 17

By angle and square root

Question 18

WHat is congruent

Answer 18

The same shape and size,

Question 19

QUadateral is a __ shape and must add up to __ degrees

Question 20

What id SOH, CAH, TOA and when to use

Answer 20

Sin(θ) = Opposite / Hypotenuse. CAH: Cos(θ) = Adjacent / Hypotenuse. TOA: Tan(θ) = Opposite / Adjacent. We can use SOHCAHTOA to find a missing side of a right angled triangle when we have another side and a given angle. We can use SOHCAHTOA to find a missing angle of a right angled triangle when we have two given sides.

Question 21

What happens when two lines are perpincudlar to ta third line

Answer 21

Those two lines become parallel

Question 22

if two angles add up to 90°, the sine of one equals the cosine of the other.

Answer 22

the sine of one equals the cosine of the other A bit of notation applies here: when we want to know what the sine of an angle is, say, the sine of angle A, we write “sin A.”

Question 23

what are vertical angles, corresponding angles, alternate interior angles, and supplementary line?

Answer 23

vertical angles are angles formed by the intersection of two lines while alternate interior angles, alternate exterior angles, corresponding angles and consecutive interior angles are formed by the intersection of two lines and a transversa. Supplemlnmary line add up to 180 degrees.

Question 24

Exterior angle theorem

Answer 24

states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles.

Question 25

An isoleoces triangle has

Answer 25

An isoleoces triangle has two same sides, and two same angles.
and the opposite angles are equal to each other. Ex =. If AB=AC. Then angle B and C are = to each other.

Question 26

Pythagorean triplets. Name 2 of them

Answer 26

Pythagorean triplets. (3,4,5) (5,12,13) are the most common

Question 27

Right troiangles and triangle ineqlaity theorem. How to solve right triangles

Answer 27

Every right triangle obeys the pythagroem theorem. A squared + b squared = c squared.
Where C is the hypotensue.
triangle ineqlaity theorem. states that the sum of any two sides of a triangle is greater than or equal to the third side; in

Question 28

Special right triangles (you have to meorize two special triangles relationship)

Answer 28

45-45-90 angle. = x on adjacent and opposite. And x square root 2 on hypotenuse
30-60-90 angle. = x on opposite. 2x on hypostnue and x square root 3 on adjacnet

Question 29

Similar triangles and congruent triangles

Answer 29

you can find Similar triangles, by AA, SAS, SS. Example if one triangle has a side of 3 and 4, the other has 9 and 12, they are similar.

Similar triangles have the same shape but sizes may vary but congruent triangles have the same shape and size. You can solve them using the formula x1/x2=y1/y2. This is different than averages ratios because you use the same line for x’s and the same line for y’s.

Question 30

Radian (pi raidan =) converting radian to degree and vice versa. How much radian in a circle

Answer 30

Radian (pi raidan = 180) There are 2π radians in a whole circle, which means that half a circle (180°) is equal to π radians.

Question 31

What is Soh-cah-toa. When to use soh-cah toa, and Patherigm theorm, And how to use it when you have one angle? What is sin 90, cos 90, tan 90. What is sin 0, cos 0, tan 0. What is Cos x, and Sin x. What is Sin b, if Cos a = 2, if they are completmary lines.

Answer 31

Example if you have an angle of 43, an unknown opposite and a hypotenuse of 12. You would use SOH. So it would be sin43 = x/12. Then you multiply each side by 12. Then you first do SIN 43 = 0.681. Then multiply it by 12 which gives you 8.18. Sin x = cos(90-x) . COs x = sin(90-x)
Sin 0 = o. Cos 0 = 0. Tan 0 = 0. Sin 90 = 1. Cos 90 = 0. Tan 90 = undefined. Sin b= cos a.

. Use soh-cah-toa when youhave an angle and 2 side lengths. Use theorem theorem when dealing with only sides.

Question 32

Area of a circle

Answer 32

Area of a circle is: pi*R squared

Question 33

Circumference of a circle:

Answer 33

Circumference of a circle: 2pi*R

Question 34

Arc length: and sector area

Answer 34

Arc length: angle/360 * circumference. Or Central angle/360 = arc length/ circumference. Can use if you have 3/4. Area of the sector. Central angle/360 = area of sector/ area of circle.

Question 35

The measure of an arc is the
