Question

matching identify the following triangles by its sides. (g5a) 1. a) equilateral 1. 2. b) isosceles 2. 3. c) scalene 3.

Explanation:

Step1: Recall triangle side 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 each triangle

• For the first triangle (assuming it has all sides different - since no side - length markings are clear but if it's a general scalene - like figure), it is a scalene triangle.
• For the second triangle (with two sides marked as equal - 10 and 10), it is an isosceles triangle.
• For the third triangle (with all sides marked as equal - the tick - marks on all three sides), it is an equilateral triangle.

Answer:

1. C. Scalene
2. B. Isosceles
3. A. Equilateral
