Geometry

Question 0

Explain the SAS rule of congruent triangles.

Answer 0

Side angle side.

If you have two know lengths with an angle in the middle, the triangle set in size and shape.

Question 1

Explain the ASA rule of congruent triangles.

Answer 1

Angle side angle. If you have a set length with two set angles on each side, the triangle is fixed.

Question 2

Explain the SSS rule of congruent triangles.

Answer 2

Side side side. If you have the three sides of a triangle, it is set in size and shape.

Question 3

Explain the RHS rule of congruent triangles.

Answer 3

Right angle, hypotenuse, side.
If you know that the triangle has a right angle, the length of the hypotenuse and another side, the triangle will be fixed in size and shape.

Question 4

What are all the abbreviated rules of congruent triangles?

Answer 4

SSS, ASA, SAS, RHS

Question 5

How is the exterior angle calculated?

Answer 5

360 divided by the number of sides

Question 6

How is the interior angle calculated ?

Answer 6

180- exterior angle.

Question 7

How is the total of the interior angles calculated ?

Answer 7

(N-2) X 180

Minus 2 from the number of sides and multiply by 180.

Question 8

How is the sun of the exterior angles calculated?

Answer 8

It is always 360.

Question 9

How is the sine rule used for sides?

Answer 9

Use the equation on the formula sheet.

Multiply the complete fraction by sin of the opposite angle.

Question 10

How is the sine rule used for angles?

Answer 10

Reverse the equation they give you on the equation sheet.
The angle is sin-1 to the whole fraction.
However have the length of the line opposite the angle you want in front is the sin in your fraction e.g. 34sin-1
