Geometry

Question 1

a quadilaterial can be cut in half into two trraingles

Answer 1

ma

Question 2

hexagon can be cut into two traingles

Answer 2

z throuhg the middle

Question 3

height of equaliteral traingle is always one half the side time square 3

Answer 3

angles

Question 4

ratio of sides of 30-60-90 traingle

Answer 4

is 1/2/square 3

Question 5

ratio of sides of right traingle 45 45 90

Answer 5

is 1/1/ square 2

Question 6

a straight line has a measurement of 180 degrees

Answer 6

Pperpeiendicular lines are lines that interesct at a 90 degree angle

Question 7

the interior formed from interesciting lines form a circle

Answer 7

• 360 degees

Question 8

Acute angles ( es than 90 degrees

Answer 8

obtuse angles greater than 90 degrees

Question 9

Acute angles ( es than 90 degrees

Answer 9

obtuse angles greater than 90 degrees

Question 10

three dimesnionsl

Answer 10

surface area= sum of all the faces

Question 11

to find surface area of a cub you only need length of one side

Answer 11

first find the area of one face (5x5) then multiply by six to acount for all the faces 6 x 25=150

Question 12

there are two types of right traingles

Answer 12

45-45-90 or 30-60-90

Question 13

angles correspond to their opposite sides

Answer 13

meaning largest angle is opposite the longest sidee…

Question 14

the sum of any two sides of a traingle must be greater than the third side

Answer 14

beware of the impossible traingle

Question 15

common combinations of right traingle

Answer 15

3-4-5, 5-12-13, 8-15-17

Question 16

Isoscles traingle (45-45-90)

Answer 16

x, x, x square root

Question 17

Equaliaterial traingles all three sides and angle (60) are equal

Answer 17

30 degree angle = x (side) 
60 degree angle = x square root 3
90 degree (hypotnuse)= 2x

Question 18

traingles are defined as similar if all of their corresponding anlges are equal and their correspoinding sides are in porpotion

Answer 18

once you know that the traingles have two pairs of equal angles you know that traingles are similar

Question 19

slope= rise/run

Answer 19

to find the rise subtract the y cordinatres

to find the run subtract the x cordinates
