Sagot :
3 Answers: Choice A, Choice C, Choice E
=====================================================
Explanation:
Let's go through the answer choices to see which are true and which are false.
- A) True. The base angles are the same measure, and they are opposite the congruent sides. Any isosceles triangle has exactly two congruent sides.
- B) False. This is describing an equilateral triangle (where all three angles are 60 degrees each).
- C) True. See choice A.
- D) False. This is describing an equilateral triangle where all sides are the same length.
- E) True. You can use the SAS (side angle side) congruence theorem to prove that the angle bisector is also the perpendicular bisector. Furthermore, this segment is also a median. This only applies to the vertex angle.
Answer:
The base angles are congruent.
The two sides opposite the base angles are congruent.
The bisector of the vertex angle is the perpendicular bisector of the base.
