a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
Let r be the angle of the ray, and R the angle of reflection.If the wall is flat (i.e., if its angle is 0), then we know that r + R = Pi/2.Now suppose the wall has angle w. Then rotate the diagram by -w,so that the wall is now flat again, and the angles of the ray and itsreflection are now r - w and R - w, respectively.We then have (r - w) + (R - w) = Pi/2, which should give you enoughinformation to find R.
Exterior angle regular polygon = 360° ÷ number of sides = 360° ÷ W Interior angle regular polygon = 180° - exterior angle regular polygon = 180° - (360° ÷ number of sides ) = 180° - (360° ÷ W)
A 7 sided shape is a heptagon.
A pentagon is a shape that has 5 sides.
Measure of an angle, mean and midpoint are geometric terms.
26 degrees
the average angle is acuite w/ obtuse * * * * * An incorrect answer.
The question is not very coherent. However if the sides either side of BC are able to meet at a point, then the angle between BC and the adjacent sides must be less than 90 degrees. Hence the shape can only be a triangle and since it's regular the angle must be 60 degrees. So if n is 3, the angle (60) is 20n.
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
It is an obtuse angled triangle.
acute angle

The letter "w" has three acute angles.
Almost all of us would say that angle is a scalar quantity. But the beauty is that angle is a vector quantity. Now the question arises. Where will be the direction? As we measure the angle in a plane in counter clockwise direction, then direction of angle vector will be perpendicular to the plane and coming out of the surface. If the angle is measured in clockwise then vector would go into the surface normally. As angle becomes vector then angular velocity w = @/t also becomes a vector.
