When you add all four sides of a quadrilateral(all parallelograms are quadrilateral), It must equal 360 degrees. So what you do is you add up the three angles that are given, them subtract that sum from 360.

How do you find missing angle of a parallelogram?

Being a quadrilateral, the sum of all four angles is 360o.Opposite angles of a parallelogram are equal.Adjacent angles of a parallelogram are supplementary, that is add to 180o.Given one angle of a parallelogram, the other 3 angles can be calculated:the opposite angle is the same;the other two angles are the same as each other and are 180o - the_given_angle


How do you find the adjacent angle sum of parallelogram?

You do not need to find. If it is a parallelogram, it must be 180 degrees.


How can you find a missing side or angle of a right triangle?

180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.


What angle does the height intersect with the base of a parallelogram?

The height is a perpendicular angle from the base. The sides of the parallelogram are slanted tho and this will vary for every parallelogram. To find the height you typically make a triangle with one of the slanted sides.


What is the first step when trying to find a missing angle?

If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.


How do you find an angle of a parallelogram using sides?

You cannot. A parallelogram can be flexed: the angles can be altered without affecting the lengths of the sides.


How do you find a missing angle for a triangle?

Subtract the two known angles from 180 degrees will give you the missing angle


Is a parallelogram with a right angle a square?

Yes a parallelogram with a right angle is a square.


What is the missing angle of triangle that has a 53 degree angle and a 34 degree angle?

the missing angle is 93 degrees. you find that out by adding 53 and 34 and then subtracting them from 180. :)
