Two triangles are considered to be similar if for each angles in one triangle, there is a congruent angle in the other triangle.
Two triangles ABC and A'B'C' are similar if the three angles of the first triangle are congruent to the corresponding three angles of the second triangle and the lengths of their corresponding sides are proportional as follows: AB / A'B' = BC / B'C' = CA / C'A'

What is the branch of mathematics in which you learn about triangles?
Geometry.
Why trigonometry taught as a part of mathematics?
Because it is a branch of mathematics that is concerned with measurements of angles and sides of triangles, and following from that, areas and other characteristics.
What is the similarities of a triangular prism and a pyramid?
They are both 3d and they both form triangles on the sides to come up and make a point
What are uses of similar triangles in daily life?
Similar triangles can be used in many situations in which angles of two differently-sized triangles are the same. Optics, scale modeling,trigonometry, surveying, astronomy, and many, many other applications of mathematics rely on the concept of similarity.
Are all acute triangles the same?
Mathematics is a discipline where exactitude is all-important.Whether all acute triangles are 'the same' depends on what you mean by same. Here are some possibilities for 'same', and whether all acute triangles qualify.The triangles are congruent (one fits exactly on top of another) ? No.The triangles are similar (same three angles) ? NoEach of the three angles is less than 900 ? YesSame no of sides ? YesA polygon ? Yes.A plane figure ? Yes.All acute triangles meet the last four criteria; some may meet the first two as well, but not all of them.
