What does a right angle look like?

True, see solution.

Practice makes perfect

The given equation, m∠ ABC=90^(∘), tells us that the measure of ∠ ABC is 90^(∘). The symbol at the angle's vertex indicates that it is a right angle.

Since all right angles are 90^(∘), ∠ ABC is in fact 90^(∘). Therefore, this is a true statement.
