Let’s go through each shape one by one and look at the angle that is marked.
---
First Shape: Star
The marked angle is in one of the points of the star. It looks sharp — smaller than a right angle (which is like the corner of a square). Angles smaller than 90° are called
acute angles.
✔ So, for the star →
Acute Angle
---
Second Shape: Trapezoid
The marked angle is at the top right corner. It looks wider than a right angle — bigger than 90°. Angles bigger than 90° but less than 180° are called
obtuse angles.
✔ So, for the trapezoid →
Obtuse Angle
---
Third Shape: Pentagon-like shape with a square corner
The marked angle has a little square symbol in the corner. That symbol always means it’s exactly 90° — a
right angle, like the corner of a book or a window.
✔ So, for this shape →
Right Angle
---
Final Answer:
- First shape (star): Acute Angle
- Second shape (trapezoid): Obtuse Angle
- Third shape (pentagon with square corner): Right Angle
Parent Tip: Review the logic above to help your child master the concept of worksheet identifying angles.
