What are the differences between a triangle and an octagon?
Triangle has 3 sides, 3 vertices (corners) whose interior angles add up to 180. Octagon has 8 sides, 8 vertices, whose interior angles add up to 1080 degrees. A regular triangle (all sides equal, all angles equal), has interior angles of 60 degrees. A regular octagon (all sides equal all angles equal), has interior angles of 135.
What is the measure of one of the interior angles in a square?
All of the angles in a square are equal, and are 90 degrees.
Why does a parallelogram equal 360 degrees?
The interior angles of all quadrilaterals sum to 360 degrees. Since a parallelogram is a quadrilateral, its interior angles must sum to 360 degrees.
Is a rectangular having all angles equal?
The 4 interior angles of a rectangle each measure 90 degrees
What is the interior and exterior angle of a p sided polygon?
Sum of interior angles = (p-2)*180 degrees Sum of exterior angles = 360 degrees You can go further than that only if the polygon is regular. In that case, all the interior angles are equal and each one is (p-2)*180/p degrees; and all the exterior angles are equal and each is 360/p degrees.
