Which shape has some perpendicular sides but no parallel sides?
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
Is there an algebraic formula for determining an angle of reflection using only the angle of the ray and the angle of the wall?
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.
How do you work out the exterior and interior angles of a regular polygon with W sides?
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)

What is a shape w 5 sides called?
A pentagon is a shape that has 5 sides.
What geometry words start with the letter W?

The average angle measure of a trapezoid?
the average angle is acuite w/ obtuse * * * * * An incorrect answer.
BC is one side of a regular n-gon the sides next to BC are extended to meet at W Find the measure of angle W in terms of n?
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.
Which shape has some perpendicular sides but no parallel sides?
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.

It is an obtuse angled triangle.
What kind of angle is the letter W?
acute angle
