1-5 Practice

Explain how we know triangle ABC is equilateral?

How many equilateral triangles are there in this diagram?

Select all the true statements.

Select all statements that must be true.

Select all segments that have the same length as segment AC.

Starting with points A and B, re-arrange the following straight-edge and compass construtions to construct the diagram.

1. Label the points where the circles intersect C and D.
2. Draw circle with center B and radius BA, and circle A with radius AB.
3. Use a straight-edge to draw segments AC, CB, BD, and DA.
4. Use a compass to find the length of segment AB.
5. Locate the points where the circle A and circle B intersect.
