a coordinate plane
A pyramid has 6 angles, 8 faces, and 6 edges. Is that right?
Perpendicular lines formed right angles.
A perpendicular line is formed when two lines meet at a right angle. Opposite angles in a perpendicular line are parallel to each other.
180 Degree.
A square...!?!
A pentagonal prism has 10 right angles, formed from perpendicular edges. It has one for each angle made when a face meets a base. Since it has 5 faces and 2 bases, there are 10 right angles.
Coordinate Plane
That would be a rectangle.
Octagon.
a coordinate plane
Right angles (or 90 degrees).
A pyramid has 6 angles, 8 faces, and 6 edges. Is that right?
Yes because they meet at right angles
A regular octagon.
Perpendicular lines formed right angles.
Normally four but there could be six if the opposite edges at the apex met at right angles.
