Question

Use the figure part 2 A​

Answer 1

Angle D = Angle CED, then CD=CE.

b) Converse of Base Angle Theorem

Explanation:

The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.

Answer 2

see explanation

Explanation:

If ∠ D ≡ ∠ CED then CD ≡ CE

The base angles theorem states that if the sides of a triangle are congruent, that is isosceles triangle the the angles opposite these sides, the base angles, are equal.

Here we are using the converse of base angle theorem (b)

That is if 2 angles are congruent ( base angles ) then the sides opposite these angles are congruent.
