Answer 1

Explanation:

Triangles:

• Scalene triangle: If the measurements of all the three sides are different, then it is a Scalene triangle.
• Isosceles triangle: If the measurement of any two sides are congruent, then it is Isosceles triangle. And so in isosceles triangle, the angles opposite to equal sides will be congruent.
• Equilateral triangle: If the measurement of all the sides are congruent, then it is equilateral triangle. And in equilateral triangle, all angles are congruent and each angle is 60°
