Question 34

Question. 34

If the arms of an angle on the paper are decreased, the angle decreases.

Answer:

true

Detailed Answer with Explanation:

Step-by-step:

  • An angle has a common point (vertex) and two arms (rays).
  • The size of an angle tells how wide the opening is.
  • Keep the vertex fixed. Move the arms closer to each other.
  • The opening becomes smaller, so the angle measure becomes smaller.
  • Example:

Start: \(60^\circ\)

Move arms closer: \(50^\circ\)

Closer again: \(40^\circ\)

Therefore, when arms move closer, the angle decreases. The statement is true.
