A square or a rectangle.
4 perpendicular lines (Assume that it is perpendicular)----> # 2 lines intersected made 4 right angles. 4 lines make 16 right angles. 4*4=16
Extend all the lines of a right-angled triangle with sides of 3, 4 and 5 units. The extension of the lines forming the right angle will produce 3 other right angles. The extension of the lines forming the other two angles will produce 6 other angles. This gives a total of 12 angles, 4 of which are acute, 4 right and 4 obtuse.
Perpendicular lines.
4 corners 4 angles Angles add up to 90' All angles are right angles Has 4 lines of symmetry
A parallelogram
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.
A square has 4 sides or lines that are equal in length and has 4 right angles.
