If two triangles are congruent then the perimeters are equal?
Yes.
Are the perimeters equal if two triangles are congruent?
Yes
Is it true that when equilateral triangles have equal perimeters they must also have equal areas?
Yes.
Does an isosceles triangle have two sides of equal length?
The definition of an isosceles triangle is a triangle with at least two sides of equal length, which means it also has two angles of equal measurement. As such, equilateral triangles; triangles in which all sides and angles are congruent (Of the same size) are also considered to be isosceles triangles.
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.
If two triangles are congruent then the perimeters are equal?
Yes.
Are the perimeters equal if two triangles are congruent?

Yes.
Is this statement below true or falseThe perimeters of the triangles are equal?
false
Do icosceles triangles have all 3 sides equal?
No. Isosceles triangles have two sides of equal length.
What is the difference between an isosceles and an scaline triangle?
An equilateral triangle is a triangle where all of the sides are of equal length. An isosceles triangle is a triangle that has only two sides that are of equal length.
What type of triangles has three side of equal length?
Equilateral triangle
Can any two triangles be joined to make a rhombus?
No. A rhombus has all four sides of equal length. To split a rhombus into only 2 triangles, it must be split along a diagonal; which means that 2 of the sides of one of the triangles must be the same length as the sides of the rhombus, which being equal mean the triangles must be (at least) isosceles - scalene triangles will not work. Further, as the diagonal will be a common length to each of the triangles (the length of their third sides), it will form the base (ie the side opposite the vertex between the sides of equal length) of the isosceles triangles, and so the triangles must be to congruent isosceles triangles. If the diagonal has the same length as the side of the rhombus, then the two congruent triangles will be congruent equilateral triangles.

What is a statement for equilateral triangles?
They are triangles whose three sides are equal in length and whose three interior angles are equal in measure.
How many sides of equal length are on an isosceles triangles?
two
Are isoceles triangles equilateral?
No but 2 sides are equal in length
