3 sided geometric figures
angles are congruent. That is sufficient to force the corresponding sides to be proportional - which is the other definition of similarity.
A angle that sums up to 180 degress
Search Definition of Congruency
It means the measurements and properties of 3 sided shapes such as triangles
Trigonometric ratios are characteristics of angles, not of lengths. And, by definition, the corresponding angles an similar triangles have the same measures.
That's the definition of trigonometry. Triangles are completely dependent upon their side lengths, and can be defined by only three values.
The study of the ratios of the sides and angles of triangles in the same plane.
By definition, all triangles have 3 sides.
A round chart divided into triangles showing sizes of various things.
No triangle has six sides. All triangles by definition have three sides.
Yes, similar triangles are congruent because in order to be congruent they must first be equal. Which in turn is the definition of a similar triangle. A triangle equal in angle measurements and/or side lengths. So, yes.
Two triangles are congruent if their corresponding sides are equal in length, and their corresponding angles are equal in measure.
