What criteria would show that two triangles are similar?
Two triangles are similar if they meet one of the following criteria: (1) the corresponding angles of the triangles are equal (Angle-Angle or AA criterion), (2) the lengths of corresponding sides are proportional (Side-Side-Side or SSS criterion), or (3) two sides of one triangle are proportional to two sides of the other triangle, and the included angles are equal (Side-Angle-Side or SAS criterion). These conditions ensure that the triangles have the same shape, though they may differ in size.
If two triangles have three pairs of congruent angles are the triangles guaranteed to be congruent?
No- triangles with all angles respectively equal need not be congruent. For example, all equilateral triangles have 3 angles of 60 degrees each but the the sides could be any length. However the sides of such triangles are proportional - such triangles are called similar. They look alike except for their scale.
Which is not a way to prove two right triangles are congruent ll or ha or hl or AA?
aa. If the angles are equal and the triangles are right triangles, then all three angles are equal, but the sides can grow or shrink, as long as they remain proportional.
If two sides of one triangle are proportional to two sides of a second triangle and the included angles of those sides are congruent then are the triangles similar?
If the 3 sides are proportional by ratio and the angles remain the same then the two triangles are similar
What is the term for two triangles whoSe angles are congruent and sides are proportional?
Such triangles are similar.
If two triangles are equiangular then their corresponding sides are proportional?
Yes.
Is it possible for two triangles to have two pairs of sides that are proportional without the triangles being similar?
Yes. You can even have two triangles with two pairs of sides that are the SAME measure without the triangles being similar.

It is not an axiom, but a theorem.

Are all equilateral triangles are similar?
DFN: we call a triangle equilateral if all sides of the triangle are the same length DFN:we call two triangles similar if corresponding angles are equal, and corresponding sides are proportional. First show that all corresponding sides are proportional: Consider a equilateral triangle with side lengths 1, all other equal lateral triangles sides can be expressed as S*(1), where S is some scalar. Hence all equilateral triangles sides are proportional to each other. Next, show that all corresponding angles are equal: The angle between two sides of a triangle is related to the length of the sides. These relationships are called sin, cos, and tan. Knowing that the cos(x), where x is one of the angles in the triangle, is the adjacent divided by the hypotenuse we see that cos(x)=(1/2)c/a, since a = c (because its equal lateral) we are left with cos(x)=(1/2) which means x = 60 degrees. this can be applied to all three angles, which shows that all three angles are 60 degrees. / \ / | \ a / | \ b /__ |__\ c We have now shown that all equal lateral triangles are similar because they all have proportional sides, and they all have equal angles.
