Answer:
Option A, Sketch a triangle with congruent base angles
Step-by-step explanation:
<u>Step 1: Determine which is correct</u>
Option A: This option is correct because to have a triangle with congruent base, that means that two of the sides have to be the same length. This produces angles B and C to be equal. That is what it means by congruent base angles.
Option B: This option is not correct because we do not see that all of the angles are the same. Therefore, not all of the angles are equal. Which means that it is not an equilateral triangle.
Option C: This option is not correct because when you look at the sketch, all of the angles can be seen less than 90 degrees which means all of the angles are acute.
Option D: This option is not correct because as I told in the previous answer, all of the angles are acute.
Answer: Option A, Sketch a triangle with congruent base angles
