Are two obtuse triangles always similar?
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
Two triangles that have the same angles?
The triangles are similar, but not necessarily congruent.
If two triangles are congruent are they similar?
yes
What do two triangles need to have in common in order to be similar?
similar sides.
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
Are two obtuse triangles always similar?
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
Is sss a way to find if triangles are similar?
Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other.When two triangles have corresponding sides with identical ratios, the triangles are similar.Of course if triangles are congruent, they are also 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
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.
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.
If two triangles are congruent are they similar?
yes
Are acute triangles similar?
Not necessarily. Just because two triangles are both acute doesn't make them similar. They could be similar, but not necessarily.
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
What do two triangles need to have in common in order to be similar?
similar sides.
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
