### What is two triangles with corresponding angles and corresponding sides congruent called?

They are congruent triangles.

### What are two triangles that have the same shape but are different sizes called?

Those would be SIMILAR triangles.

Two triangles

### Are triangles equilateral?

Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.

### Is it possible for two triangles to have equal angles but not equal sides?

Yes and they would be called similar triangles

### What are triangles with two congruent sides called?

an isosceles triangle

Similarity.

### What is a scale factor on a triangle?

If two triangles are similar, then the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles

Scalene Triangle

### What is a prism with triangular faces called?

If it has only two triangles then it is a triangle based prism. If it is has two n-sided polygonal faces and n triangles then it is a n-polygonal antiprism.

### Do triangles have at least one right angle?

Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90&ordm;) right triangles - one right angle (90&ordm;) and two acute angles obtuse triangles - one obtuse angle (larger than 90&ordm;) and two acute angles

### Are angles in an isoceles triangle equal?

Isosceles triangles have at least 2 equal angles. The 3rd angle can either be equal to the other two (it's then called an equilateral triangle), or it can be different from the two equal angles, in which case it's an isosceles triangle. All equilateral triangles are isosceles triangles, but not all isosceles triangles are equilateral triangles.
