What is a Similar triangles?
Two triangles are said to be similar if the ratio of the sides of one triangle to the corresponding sides of the other triangle remains the same. One consequence is that all corresponding angles are the same.
How can you tell if two triangles are similar?
Their corresponding angles are equal, or the ratio of the lengths of their corresponding sides is the same.
What is a three sided polygons with the same shape but not the same size are called?
Three sided polygons would be triangles. Triangles that have the same shape (same angle measures) but are different sizes (different side lengths) would be called similar triangles. In similar triangles, corresponding sides have lengths in the same ratio. If triangle ABC is similar to triangle DEF, then: AB/DE = BC/EF = AC/DF.
Are two arbitrarily chosen equilateral triangles similar?
Yes. Corresponding angles of the two triangles are always equal, and lengths of corresponding sides are always in the same ratio.
Is tangent in geometry and tangent in trigonometry same?
Yes a tangent is a straight line thattouches a curve at only one point But there is a tangent ratio used in trigonometry
