How do you indicate congruent angles in a diagram?

To indicate congruent angles in a diagram, you can use special markings or notation. Here are a few common ways:

1. Using an arc: Draw small arcs on the angles that are congruent. The arcs should have the same length and curvature to indicate their congruency.

2. Using tick marks: Draw tick marks (small lines) of the same length on the angles that are congruent. The tick marks should be placed at the vertex of the angles.

3. Using equal signs: Label the congruent angles with the letter 'A' and use an equal sign to indicate their congruency. For example, if angle A is congruent to angle B, write it as "∠A = ∠B".

Remember, when indicating congruent angles, it's important to make sure that the markings or notation you choose are consistent and easily understandable to others.

I hope this helps! If you have any further questions, feel free to ask.

yes

by using dashes on side lengths and/or same number of arcs in the angles

.. by marking the equal angles using the same symbol.

Sometimes a small letter like x or o is used, other times I have seen an arc drawn in each of the equal angles, a double-arm arc for the second set of equal angles etc.

As long as you use a unique symbol, all is fair.
