Geometry Unit 4 Answer Key Grade 5 Question 3.
Texas Go Math Grade 5 Unit 4 Answer Key 4
Answer:
The given figure is:

Now,
We know that,
If the angle is 90°, then it is a “Right angle”
If the angle is less than 90°, then it is “Acute angle”
If the angle is greater than 90°, then it is “Obtuse angle”
Hence, from the above,
We can conclude that
The given figure is a “Right angle”

Question 4.

Answer:
The given figure is:

Now,
We know that,
If the angle is 90°, then it is a “Right angle”
If the angle is less than 90°, then it is “Acute angle”
If the angle is greater than 90°, then it is “Obtuse angle”
Hence, from the above,
We can conclude that
The given figure is an “Obtuse angle”

Question 5.
Texas Go Math Grade 5 Unit 4 Answer Key 6
Answer:
The given figure is:

Now,
We know that,
If the angle is 90°, then it is a “Right angle”
If the angle is less than 90°, then it is “Acute angle”
If the angle is greater than 90°, then it is “Obtuse angle”
Hence, from the above,
We can conclude that

Write intersecting, parallel, or perpendicular to describe the numbered sides.

Question 7.
Texas Go Math Grade 5 Unit 4 Answer Key 8
Answer:
The given figure is:

Now,
We know that,
When two lines intersect and they don’t have an intersecting angle of 90°, they are “Intersecting Lines”
When two lines do not intersect, they are “parallel lines”
When two lines intersect and  have an intersecting angle of 90°, they are “Perpendicular Lines”
Hence, from the above,
We can conclude that
The numbered sides are “Perpendicular lines”

Question 8.
