We recall that we construct a congruent angle with a compass and straightedge by sketching a ray  𝐴 𝐺 , where 𝐴 will be the vertex of the congruent angle. We then trace a circle centered at 𝐸 that intersects the edges of the angle at two points, 𝐷 ′ and 𝐹 ′ .

What is the first step in constructing a congruent angle?

Draw an arc that crosses both rays of the original angle.

Set the point of the compass at point B, the vertex of the original angle, and draw an arc that crosses both Ray BA and Ray BC. You do not need to draw an entire circle. For reference, mark the points where the arc crosses the rays as points X and Y.

Which of these is a correct step in constructing angles?

Final answer:

The correct step in constructing congruent angles is to use a compass and draw an arc across both the legs of the given angle. The intersection of this arc with the line will provide the endpoint for one leg of the new, congruent angle.

What angle is congruent to ∠ A?

Congruent Angles Symbol

If ∠A and ∠B have the same measure, then they are said to be equal or congruent. That means ∠A is congruent to ∠B and ∠A = ∠B or ∠A ≅ ∠B.

What happens if the angles are congruent?

Congruent angles have the same angle measure. For example, a regular pentagon has five sides and five angles, and each angle is 108 degrees. Regardless of the size or scale of a regular polygon, the angles will always be congruent.

How do you prove angles are congruent?

If two angles are supplements of the same angle (or congruent angles), then the two angles are congruent. Congruent Complements Theorem: If two angles are complements of the same angle (or congruent angles), then the two angles are congruent. All right angles are congruent.

What are two methods of constructing a congruent angle?

Two methods to construct congruent angles are the compass and straightedge method and the protractor method. The compass and straightedge method uses arcs to create an identical angle, whereas the protractor method involves measuring the original angle's degree measurement and replicating it.

What is the geometric construction of angles?

To construct an angle with any degree of measure, we need to make use of a geometric tool called a compass. Once a ray is drawn, a compass is used to mark arcs according to any measured radius. These arcs intersect each other at various points which form perpendicular lines that make an angle.
