(2 x 16 - 4) right angles = 28 right angles = 28 x 90 = 2520 degrees
-- Every rectangle has four interior right angles.-- Every square is also a rectangle, so the question is describing a total of four rectangles.-- (4 rectangles) x (4 right angles per rectangle) = 16 right angles
A pyramid has 6 angles, 8 faces, and 6 edges. Is that right?
16 - four in each !
A square pyramid has 16 angles.
Draw four perpendicular lines that cross each other. Like this: # except at right angles. Count the angles - 4 in the centre square, and 12 around the overlapping parts.
16 angles, 8 of each measure - unless the transversal is perpendicular in which case, all 16 angles are right angles.
I believe that an octagon has 16 lines of symmetry.

A pyramid has 6 angles, 8 faces, and 6 edges. Is that right?
A rectangle has 4 right angles. There are no acute angles.

Including those at the boundaries of the flag, there are 16.
