Eureka Math Grade 4 Module 4 Lesson 3 Problem Set Answer Key

Question 1.
On each object, trace at least one pair of lines that appear to be perpendicular.
Eureka Math Grade 4 Module 4 Lesson 3 Answer Key (1)
Answer:
When two distinct lines intersect each other at 90 degrees those lines are called perpendicular lines.

Explanation:
Eureka Math Grade 4 Module 4 Lesson 3 Answer Key (2)

When two distinct lines intersect each other at 90 degrees those lines are called perpendicular lines. A right angle is also known as perpendicular lines. In the above images, we have traced out the perpendicular lines and the properties of perpendicular lines are these lines should always intersect at right angles. So if the two lines are perpendicular to the same line then those lines will be parallel to each other and will never intersect.

Question 2.
How do you know if two lines are perpendicular?
Answer:
When two distinct lines intersect each other at 90 degrees those lines are called perpendicular lines. A right angle is also known as perpendicular lines. And the properties of perpendicular lines are these lines should always intersect at right angles. So if the two lines are perpendicular to the same line then those lines will be parallel to each other and will never intersect.

Question 3.

Answer:
As two distinct lines intersect each other at 90 degrees those lines are called perpendicular lines. A right angle is also known as perpendicular lines. And the properties of perpendicular lines are these lines should always intersect at right angles. So if the two lines are perpendicular to the same line then those lines will be parallel to each other and will never intersect.

In the above image, we have constructed the perpendicular lines, as two distinct lines intersect each other at 90 degrees those lines are called perpendicular lines. A right angle is also known as perpendicular lines. And the properties of perpendicular lines are these lines should always intersect at right angles. So if the two lines are perpendicular to the same line then those lines will be parallel to each other and will never intersect.

As two distinct lines intersect each other at 90 degrees those lines are called perpendicular lines. A right angle is also known as perpendicular lines. And the properties of perpendicular lines are these lines should always intersect at right angles. So if the two lines are perpendicular to the same line then those lines will be parallel to each other and will never intersect. As in the above image a is a square the perpendicular angles are <AB and <BD, <BD and <CD, <CD and <CA, <CA and <AB. And in image b we can see that the image is polygon so there will be No Right Angles. In image c we can see some angles, so the perpendicular angles are <GE and <EF. In image d there will be No Right Angles as there as it is in oval shape and no angles in that image. In image e, there are some angles, so the perpendicular angles are <AW and <WF, <WF and <FZ, <FZ and <ZH, <AZ and <AW. In image f, there are no angles, so there will be no perpendicular angles as there are No Right Angles. In image g there are no angles, so there will be no perpendicular angles as there are No Right Angles. In image e, there are some angles, so the perpendicular angles are <VW and <WX, <WX and <XY, <YU, and <UV.

Question 6.
True or false? Shapes that have at least one right angle also have at least one pair of perpendicular sides. Explain your thinking.
Answer:
Yes, it is true. As the right angles are created by sides that are perpendicular, so if a figure has a right angle it must have perpendicular sides.

Question 6.
True or false? Shapes that have no right angles also have no perpendicular segments. Draw some figures to help explain your thinking.
Answer:
Yes, it is true. As the shapes without right angles have no perpendicular segments because perpendicular lines meet at right angles. So the rhombus has equal sides but no right angles and no perpendicular segments.
