4.6 Isoceles and Right Triangles

Question 1

Base Angles

Answer 1

The two angles that have the base as part of one side of the angle

Question 2

Base Angles Theorem

Answer 2

If two sides of a triangle are congruent, then the angles opposite them (in the same triangle) are congruent

Question 3

Base Angles Converse Theorem

Answer 3

If two angles of a triangle are congruent, then the sides opposite them (in the same triangle) are congruent

Question 4

Corollary to Base Angles Theorem

Answer 4

If a triangle is equilateral, then it is also equiangular

Question 5

Corollary to Base Angles Converse Theorem

Answer 5

If a triangle is equiangular, then it is also equilateral

Question 6

Hypotenuse-Leg (HL) Congruence Theorem

Answer 6

If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and leg of a second right triangle, then the two triangles are congruent
