Question 6.
Math in Focus Grade 4 Chapter 11 Practice 1 Answer Key Squares and Rectangles 6
Is this a rectangle? ____
Why or why not? ________
Answer:
Yes
A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral.

Question 7.
Math in Focus Grade 4 Chapter 11 Practice 1 Answer Key Squares and Rectangles 7
Is this a rectangle? ____
Why or why not? ________
Answer:
No
A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square. The above figure is a square because all sides are of equal length.

Question 8.
Math in Focus Grade 4 Chapter 11 Practice 1 Answer Key Squares and Rectangles 8
Is this a rectangle? ____
Why or why not? ________
Answer:
Yes
A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral.

Find the lengths of the unknown sides.
