Question 1

Define: Side-Angle-Side (SAS)

Answer 1

If the lengths of two sides of a triangle are proportional to the lengths of two corresponding sides of another triangle and the included angles are congruent, then the triangles are similar

Question 2

Define: Triangle Sum Theorem

Answer 2

The sum of the measures of the angles of a triangle is 180°

Question 3

Define: Angle-Angle (AA)

Answer 3

If two angles of a triangle are congruent to two angles of another triangle, then the triangles are similar

Question 4

Define: similar

Answer 4

Same shape; not equal in size

Question 5

Define: congruent

Answer 5

SAME, Equal in measure

Question 6

Define: Exterior Angles

Answer 6

Formed by one side and the extension of an adjacent side

Question 7

Define: Exterior Angle Theorem

Answer 7

i) The measure of the exterior angle of a triangle is equal to the sum of the two remote interior angles
ii) The exterior angle and its adjacent angle add up to get 180°

Question 8

Define: Acute, Right, and Obtuse

Answer 8

Acute 90° but

Question 9

Define: Acute Triangles, Right Triangles, and Obtuse Triangles (By Angles)

Answer 9

Acute Triangle: ALL angles are less than 90°
Right Triangle: one angle is equal to 90°
Obtuse Triangle: one angle is greater than 90°

Question 10

Define: Acute Triangles, Right Triangles, and Obtuse Triangles (By Sides)

Answer 10

Scalene: ALL sides have different lengths
Isosceles: two sides have the same lengths
Equilateral: ALL sides have the same length

Question 11

Define: Side-Side-Side (SSS)

Answer 11

If the corresponding sides lengths of 2 triangles are proportional, then the triangles are similar
