A triangle has 3 edges and 3 corners. Depending on what kind of triangle it is decides what angles they are.
Hope this helped a little. :)
(You can always draw a picture that always helps me)
A triangle has 3 vertices and three sides (edges). It has one face.
3 vertices, 3 edges and 1 face.
An edge is the set of points where two (or more) planes meet. Since a triangle must be in just one plane, it cannot have any edges. It has one face, which is part of the plane containing the triangle.
4 faces/ 4 vertices/ 6 edges

A triangular prism has 5 faces, 9 edges and 6 vertices

A triangle has three sides or edges.
There are always 3 edges on a triangle, otherwise it would not be a triangle.
There are three straight edges in a triangle.
there are no curved edges on any triangle.
Three EdgesA triangle has three edges.
A triangle has three edges; a rectangle has four.
A triangle consists of three corners and three edges.
a triangle does not equal just a number. a triangle is an object that has three edges all connected at there tips. the triangle's inside angles all add up to 180 degrees. a triangle can be acute, obtuse, or right.
