What else can I help you with?
What do you call two triangles with proportional sides?
They are said to be similar but not congruent triangles.
What do similar triangles look like?
similar triangles have all the same angles in each of them, and their sides can be of any length
What is true about the angles and sides on similar triangles?
All the Angles and sides on Triangles are always going to equal 180 Degrees
What is the term for two triangles whoSe angles are congruent and sides are proportional?
Such triangles are similar.
What are triangles whose corresponding angles are equal and corresponding sides are in proportion?
Similar 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
What is true about the area of similar triangles when the sides are increased by the factor of two?
when you multiply the area of the small triangle by four it equals the area of the large triangle.
What do you call two triangles with proportional sides?
They are said to be similar but not congruent triangles.
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
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.
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.
Do similar triangles have proportional sides?
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.
Are acute-angled triangles similar?
Similar in the number of sides but not congruent
What do two triangles need to have in common in order to be similar?
similar sides.
What do similar triangles look like?
similar triangles have all the same angles in each of them, and their sides can be of any length
What is true about the angles and sides on similar triangles?
All the Angles and sides on Triangles are always going to equal 180 Degrees
