AB and BC are both radii of B.
To prove that AB and AC are congruent: "AC and AB are both radii of B." Apex.
Simply use a protractor and all 3 interior angles should each measure 60 degrees.
The following is the answer.
concave, equilateral
Straightedge Compass
-CPTCP -SSS triangle congruence postulate -all of the radii of the circle are congruent apex :)

The question isn't clear.
A "straightedge" person was originally someone who didn't do any of the following; * take/use drugs * drink any alcohol * smoke * have sex * eat dairy products * eat meat now-a-days, most kids call themselves straightedge if they don't do the top 3 in the list, and any kids that don't do anything in the list are called "hardcore straight-up straightedge kids" Answer A straightedge is a piece of wood or plastic to help in drawing straight lines. A ruler is a straightedge, but a straightedge may not be a ruler. Both have a straight edge, certainly, but a ruler also has marked gradations for measuring things.

In Euclidean geometry, the statements are true: I. The sum of the interior angles of a triangle is always 180 degrees; II. It is indeed possible to construct an equilateral triangle, as it can be done with a compass and straightedge; III. At most, a triangle has three sides, as defined by its geometric properties.
