Will the lengths of two corresponding altitudes of similar triangles will have the same ratio as any pair of corresponding sides?
It is given that two triangles are similar. So that the ratio of their corresponding sides are equal. If you draw altitudes from the same vertex to both triangles, then they would divide the original triangles into two triangles which are similar to the originals and to each other. So the altitudes, as sides of the similar triangles, will have the same ratio as any pair of corresponding sides of the original triangles.
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
Are three short cuts for proving triangles similar?
If the 3 interior angles are the same then the triangles are similar
What are triangles that have same shape and not same size called?
Similar triangles
Is angle angle angle a way to show that triangles are similar?
Yes, AAA is a way to show that triangles are similar. Note, however, that AAA is not a way to show that triangles are congruent.
Two equilateral triangles are sometimes similar?
Two equilateral triangles are always similar!
What do you call two triangles with proportional sides?
They are said to be similar but not congruent triangles.
Are two obtuse triangles always similar?
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
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.
How you can prove that the angles of two triangles are equal?
If the angles of two triangles are equal the triangles are similar. AAA If you have three angles on both triangles these must be equal for the triangles to be similar. SAS If you have an angle between two sides and the length of the sides and the angle are the same on both triangles, then the triangles are similar. And SSS If you know the three sides
Are the angle measures of similar triangles different?
for two similar triangles , their corresponding angles are equal.
Two triangles that have the same angles?
The triangles are similar, but not necessarily congruent.
The term for two triangles that are congruent after a dilation is?
The term for two triangles that are congruent after a dilation is similar.
What are two isosceles triangles with congruent vertex angles?
They're similar triangles.
Are two triangles always the similar?
Nope. You must know what it means to be similar. It means that ALL three angles are the same between two triangles. That been said, you can take any two random triangles, it's very likely that they are NOT similar.

If two triangles are congruent are they similar?
yes
