Guidelines for solving problem 3 on page 55 of Math 4 textbook
Problem Statement:
Draw square ABCD with a side length of 5cm, then examine diagonals AC and BD:
a) Are they perpendicular?
b) Are they equal?
Solution Method:
Steps to draw square ABCD when the side lengths are known:
- Step 1: Draw line DC with a length of 5cm.
- Step 2: Draw a line perpendicular to DC at D and at C. On each perpendicular line, take segments DA = 5cm, CB = 5cm.
- Step 3: Connect point A to point B to form square ABCD with a side length of 5cm.
a) Use an e-ke to check the perpendicularity of the diagonals.
b) Use a ruler to measure the length of the two diagonals.
