Explain the difference between an equilateral triangle and an isosceles triangle.

An equilateral triangle has three congruent sides, while an isosceles triangle has only two congruent sides.

Can a triangle be both right and equilateral? Explain your reasoning.

No, a triangle cannot be both right and equilateral. An equilateral triangle has three 60° angles, and a right triangle must have one 90° angle.

A square has four congruent sides and four right angles, while a rectangle has two pairs of congruent sides and four right angles.

Classifying Polygons - How Are Different Shapes Related?

3 key concepts

1
Polygons are flat, closed shapes made of straight sides.
2
Triangles can be classified by their sides as equilateral, isosceles, and scalene, or by their angles as right, acute, and obtuse.
3
Quadrilaterals are sorted by the number of parallel sides they have; for example, a quadrilateral with two pairs of parallel sides is called a parallelogram.
