To solve the question, we need to name three shapes that can be drawn using straight lines and then count the number of right angles, angles more than a right angle, and angles less than a right angle in each shape.
Let's consider the following three shapes:
Rectangle:
A rectangle has four right angles (90°).
Number of right angles: 4
Number of angles more than a right angle: 0
Number of angles less than a right angle: 0
Acute Triangle (a triangle with all angles less than 90°):
This triangle has three acute angles (each less than 90°).
Number of right angles: 0
Number of angles more than a right angle: 0
Number of angles less than a right angle: 3
Obtuse Triangle (a triangle with one angle more than 90°):
This triangle has one obtuse angle (greater than 90°) and two acute angles (less than 90°).
Number of right angles: 0
Number of angles more than a right angle: 1
Number of angles less than a right angle: 2
To summarize the counts for each shape:
Rectangle: 4 right angles, 0 angles more than a right angle, 0 angles less than a right angle.
Acute Triangle: 0 right angles, 0 angles more than a right angle, 3 angles less than a right angle.
Obtuse Triangle: 0 right angles, 1 angle more than a right angle, 2 angles less than a right angle.
