The vertex shader is used to transform the attributes of vertices (points of a triangle) such as color, texture, position and direction from the original color space to the display space.

Look for arcs inside each vertex. The same number of arcs indicate equal angles. Different numbers of arcs indicate different angles. To identify the symmetry of a triangle: Count how many ways ...

The method involves drawing arcs with a compass, from the ends of the given line, to meet at the third vertex of the triangle. Place compass point at point R, and draw an arc using compass opened ...
