Since I can't view or access images directly, I can't see the specific angles in your uploaded image. However, I can help you solve this type of problem if you describe the angles or provide details about them.
That said, here’s how to
identify angle types based on their measure:
Types of Angles:
1.
Acute Angle: Less than 90° (e.g., 30°, 45°)
2.
Right Angle: Exactly 90° (often marked with a small square)
3.
Obtuse Angle: Greater than 90° but less than 180° (e.g., 120°)
4.
Straight Angle: Exactly 180° (forms a straight line)
5.
Reflex Angle: Greater than 180° but less than 360°

How to Identify Them from Diagrams:
- Look at the
opening between the two rays:
- If it's
small and narrow, it's likely
acute.
- If it's
exactly like an "L" shape, it's
right.
- If it's
wider than a right angle but not a full line, it's
obtuse.
- If it's a
straight line, it's
straight.
- If it's
more than a straight line (like a bent circle), it's
reflex.

Example:
If one angle has a small arc and looks sharp →
acute
If it has a square corner →
right
If it’s wide but less than a straight line →
obtuse
If it’s a straight line →
straight
If it's more than half a circle →
reflex

Please describe the angles in your image (e.g., “the first one is a small sharp angle,” or “the third one has a square symbol”), and I’ll help you label each one correctly!
Parent Tip: Review the logic above to help your child master the concept of reflex angle worksheet.
