(Notice that even when the triangular prism sits on a rectangle, the base is still a triangle.) Two of its faces are triangles; three of its faces are rectangles. It has

**six vertices**and nine edges. A rectangular pyramid has 5 faces.Also to know is, how many corners has a triangle?

A square and a rectangle each have 4 sides and

**4 angles**. The only difference between them is that a square is a rectangle with equal sides. Both have**4 90**degree (right) angles. A triangle has 3 sides and**3 angles**.What do you call the corners of a triangle?

A

**triangle**is a type of polygon having three sides and, therefore, three angles. The**triangle**is a closed figure formed from three straight line segments joined at their ends. The points at the ends can be**called**the**corners**, angles, or vertices of the**triangle**.How many corners are there in a star?

A regular star pentagon, {

**5/2**}, has**five corner vertices**and intersecting edges, while concave decagon, 5/2. , has**ten edges**and**two**sets of**five vertices**.
