### Eureka Math Grade 5 Module 5 Lesson 18 Problem Set Answer Key

Question 1.
Draw the figures in each box with the attributes listed.
a. Rhombus with no right angles
b. Rectangle with not all sides equal
c. Rhombus with 1 right angle
d. Rectangle with all sides equal

Question 2.
Use the figures you drew to complete the tasks below.
a. Measure the angles of the figures with your protractor, and record the measurements on the figures.
b. Use a marker or crayon to circle pairs of angles inside each figure with a sum equal to 180°. Use a different color for each pair.

1. 100 degrees + 80 degrees = 180 degrees
2. 90 degrees + 90 degrees = 180 degrees
3. 90 degrees + 90 degrees = 180 degrees
4. 90 degrees + 90 degrees = 180 degrees

Question 3.
Draw a rhombus and a rectangle below.
a. Draw the diagonals, and measure their lengths. Record the measurements on the figure.
b. Measure the length of each segment of the diagonals from the vertex to the intersection point of the diagonals. Using a marker or crayon, color segments that have the same length. Use a different color for each different length.

Question 4.
a. List the properties that are shared by all of the rhombuses that you worked with today.
b. List the properties that are shared by all of the rectangles that you worked with today.
c. When can a trapezoid also be called a rhombus?
d. When can a parallelogram also be called a rectangle?
e. When can a quadrilateral also be called a rhombus?

a.

Properties:

They have all the sides with equal length.

The pair of sides are parallel to each other

Their angles add up to 180 degress between to sides.

b.

All the angles are 90 degrees and both the  pair of sides are parallel and equal

c.

A treapezoid is also called a rhombus when all the 4 sides are equal

d.

A parallelogram is also called a rectangle when all the angles measures 90 degrees

e.

A quadrilateral is also called a rhombus when all 4 sides are equal and pair of sides are parallel to each other.

Question 1.
Draw a rhombus.

Question 2.
Draw a rectangle.

### Eureka Math Grade 5 Module 5 Lesson 18 Homework Answer Key

Question 1.
Use the grid paper to draw.
a. A rhombus with no right angles

b. A rhombus with 4 right angles

c. A rectangle with not all sides equal

d. A rectangle with all sides equal

Question 2.
A rhombus has a perimeter of 217 cm. What is the length of each side of the rhombus?

Given, the perimetre of rhombus = 217 cm

In rhombus, all sides are equal.

So, 217/4 = 51 1/4

Therefore, the length of each side = 54 1/4

Question 3.
List the properties that all rhombuses share.

Properties of rhombus:

a. All sides are equal

b. Their bisect bisect each other

c. Rhombuses are parallelograms , trapezoids

Question 4.
List the properties that all rectangles share.
