Question

what kind of triangle is shown below? 10 5 10 equilateral isosceles but not equilateral scalene

Explanation:

Step1: Recall triangle - type definitions

An equilateral triangle has all three sides equal. An isosceles triangle has at least two sides equal. A scalene triangle has all three sides of different lengths.

Step2: Analyze side - lengths

The side - lengths of the given triangle are 5, 10, and 10. Since two sides have a length of 10 and one side has a length of 5, it has two equal sides but not all three equal.

Answer:

B. Isosceles but not equilateral
