Question. 27

The common properties in the two set-squares of a geometry box are that they have a _____ angle and they are of the shape of a _____.

Answer:

right angle and a triangle.

Detailed Answer with Explanation:

In a geometry box, there are two plastic pieces called set-squares.
Each set-square is a right-angled triangle. This means one angle is (90^circ).
The two set-squares are of two standard types:
- Type 1 angles: (45^circ), (45^circ), (90^circ)
- Type 2 angles: (30^circ), (60^circ), (90^circ)
What is common in both?
- Both have a right angle (,90^circ).
- Both are the shape of a triangle (specifically, right-angled triangles).
