How do the ratios of side lenghts compare for triangles that are not similar?
There are no ratios that can be used for triangles that are not similar.
Are the angle measures of similar triangles different?
for two similar triangles , their corresponding angles are equal.
Why do similar triangles have the same trigonometric ratios?
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
Is the measures of corresponding angles in similar triangles the same?
No, I learned that in 6th grade
How do ratios of side lengths compare for similar triangles?
they both have the same ratios
If the ratio of the measures of corresponding sides of two similar triangles is 49 then the ratio of their perimeters is?
4.9
How do the ratios of side lengths compare for similar triangles?
The definition of "similar" geometric figures requires that the ratios of all equivalent sides, between the two figures, are the same. For example, one side of one triangle divided by the equivalent side of the other triangle might result in a ratio of 3.5 - in this case, if the triangles are similar, you will get the same ratio if you compare other equivalent sides.
How do you figure out if triangles are similar?
you compare their angles to make sure they are the same. if so, check their side lengths. if you can make a porportion, they are similar. if not, they are not similar.
If two triangles are similar are they congruent?
no: if you have two triangles with the same angle measurements, but one has side lengths of 3in, 4in, and 5in and the other has side lengths of 6in, 8in, and 10in, then they are similar. Congruent triangles have the same angle measures AND side lengths.
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 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.
What do you call two triangles with proportional sides?
They are said to be similar but not congruent triangles.
