How many congruent sides and angles do equilateral triangles have?
Equilateral triangles have three congruent sides and three congruent angles
A type of triangle with no equal sides?
There are three types of triangles. Scalene triangles have no congruent sides or angles, equilateral triangles have 3 congruent sides and 3 60degree angles, and isosceles triangles have two congruent sides and two congruent angles.
How are two angles triangles be congruent?
If they have identical sides and angles then they are congruent
Is it true that two triangles have 3 pairs of congruent angles then the triangle are not guaranteed to be congruent?
When two triangles are congruent, there are 6 facts that are true about the triangles. The triangles have 3 sets of congruent (of equal length) sides and the triangles have 3 sets of congruent (of equal measure) angles.
Are two triangles are congruent if they have the same base?
No. All corresponding sides and angles have to be congruent for the triangles to be congruent.

How are two angles triangles be congruent?
If they have identical sides and angles then they are congruent
Triangles are congruent if they have the same what?
Triangles are congruent if the lengths of their corresponding sides as well as the measures of their corresponding angles are the same.

No. All corresponding sides and angles have to be congruent for the triangles to be congruent.
If all corresponding sides and angles of two triangles are congruent those triangles are?
The triangles are also congruent.
How would you prove triangles are congruent?
You could prove two triangles are congruent by measuring each side of both triangles, and all three angles of each triangle. If the lengths of the sides are the same, and so are the angles, then the triangles are congruent... if not, then the triangles are not congruent. If the triangles have the exact same size and shape then they are congruent.
If two triangles have three pairs of congruent angles then are the triangles guaranteed to be congruent?
false
If two triangles have three pairs of congruent angles, then the triangles are guaranteed to be congruent?
false
What is two triangles with corresponding angles and corresponding sides congruent called?
They are congruent triangles.
What are necessary when proving that the opposite sides of a parallelogram are congruent?
A. Corresponding parts of similar triangles are similar.B. Alternate interior angles are supplementary.C. Alternate interior angles are congruent.D. Corresponding parts of congruent triangles are congruent
