If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. But when they move, the triangle they create always retains its shape. Thus, they always form similar triangles.

Q. What is the polygon shape?
A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A polygon.
Q. How are polygons used in real life?
Real-life applications of polygons For example: The tiles that you walk on are squared in shape, which implies that they are polygons. The truss of a building or bridge, the walls of a building, etc., are examples of polygons. Trusses are triangular in shape, while walls are rectangular shaped.
Q. What is a polygon used for?
In computer graphics, a polygon is a primitive used in modelling and rendering. They are defined in a database, containing arrays of vertices (the coordinates of the geometrical vertices, as well as other attributes of the polygon, such as color, shading and texture), connectivity information, and materials.
Q. Which types of triangles are similar?
Similar triangles
- Angle Angle Angle (AAA) If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar.
- Side Angle Side (SAS)
- Side Side Side (SSS)
- Right-angle Hypotenuse Side (RHS)
Q. Are all congruent figures are similar?
All congruent figures are similar, but the similar figures are not congruent. Congruence can be defined as “Both the figures are having the same shape, same size, everything to be equal”, whereas similarity means “same size, same ratios, same angle but different in size”.
