Explain why a square can also be named a rectangle or a rhombus.
Answer:
Explanation:
A square can be described as a rectangle because a square has 4 equal sides
and a rectangle has 2 parallel sides that are equal
In a rhombus 4 sides are equal so, A rhombus can also be called a square
Every Square is a rectangle, but not every rectangle is a square.
A square is a special kind of closed figure with four straight sides and four right angles that also have sides that all have equal length.

Look down to find the product, 24.
Look left across the row from 24.
The unknown factor is _______.
= _______
_______ × 8 = 24 Check.
_______ = 24 ✓ The equation is true.
Explanation:
24 ÷ 8 = 3
Think: 3 × 8 = 24
The unknown factor is 3.
n = 3
3 × 8 = 24 Check.
n = 24 ✓ The equation is true.
