How do you find the other 3 angles in a parallelogram when you only havethe measurement of 1 angle? (without using a protractor)
The angles in opposite corners are equal.
The angles add up to 360.
its 92 , you take your 1 angle away from 360 and divide by three then wallah! for eg:84 so..., 360-84=276 then divide by three which is,...:92!
:D d: <3 :7 :1 :0 :)
To find the other three angles in a parallelogram when you only have the measurement of one angle, you can use the properties of parallelograms. Here's how:
1. Start by drawing a parallelogram with one known angle labeled, let's call it angle A.
2. Recall that opposite angles in a parallelogram are congruent. This means that angle A is congruent to the opposite angle, which we can call angle C.
3. So, now you know the measurements of angle A and angle C. To find angle B, subtract the sum of angle A and angle C from 180 degrees. This is because the angles in any triangle add up to 180 degrees.
Angle B = 180° - (angle A + angle C)
4. Once you find the value of angle B, you can find angle D, which is opposite to angle B and congruent to it.
Angle D = Angle B
By following these steps, you can determine the measurements of all four angles in the parallelogram, even with only one known angle.
