NYS Math Module 4 Grade 4 Lesson 10 Problem Set

Write an equation and solve for the measure of ∠x. Verify the measurement using a protractor.

- ∠CBA is a right angle.
- ∠GFE is a right angle.
- ∠IJK is a straight angle.
- ∠MNO is a straight angle.

Directions: Solve for the unknown angle measurements. Write an equation to solve. - Solve for the measurement of ∠TRU. ∠QRS is a straight angle.
- Solve for the measurement of ∠ZYV. ∠XYZ is a straight angle.
- In the following figure is a rectangle. Without using a protractor, determine the measurement of ∠DEB. Write an equation that could be used to solve the problem.
- Complete the following directions in the space to the right.

a. Draw 2 points M and N. Using a straightedge, draw MN.

b. Plot a point O somewhere between points M and N.

c. Plot a point P, which is not on MN.

d. Draw OP.

e. Find the measure of ∠MOP and ∠NOP.

f. Write an equation to show that the angles add to the measure of a straight-angle.
