Right Angles and Non-Right Angles
Practice
1. Solve Exercise 3 Page 34 Math Grade 3
Problem: Use a protractor to determine which of the angles below is a right angle.
Solution Guide: Place the right angle vertex of the protractor on the vertices of the given angle. If the two edges of the right angle of the protractor coincide with the two edges of the measured angle, then it is a right angle.
Answer:
The figure above has the following right angles:
Right angle at vertex A, edges AH, AK.
Right angle at vertex B, edges BM, BN.
Right angle at vertex E, edges ET, EU.
2. Solve Exercise 4 Page 34 Math Grade 3
Problem: Use a protractor to check how many right angles each figure below has and state according to the model.
In solving this problem, utilize the angle indicator to identify the right angles in each figure. Follow the example given in two steps.
The answer is:
Quadrilateral MNPQ has 4 angles, including 2 right angles at vertices N and Q. Quadrilateral GHIK has 4 angles, with 1 right angle at vertex K.
Solve Exercise 5 on Page 34 of Math Textbook for 3rd Grade
The problem statement is:
To draw a right angle, follow these steps: - Choose a point B anywhere on the paper as the vertex of the angle. - Place the vertex of the right angle of the set square coincident with point B. - Draw 2 sides BA and BC of the angle coinciding with the two sides of the right angle of the set square; you will get a right angle with vertex B, sides BA, BC.
The solution is:
