Questions & Step-by-Step Solutions

If a parallelogram has one angle measuring 70 degrees, what are the measures of the other three angles?
  • Step 1: Understand that a parallelogram has opposite angles that are equal.
  • Step 2: If one angle is 70 degrees, then the angle directly opposite it is also 70 degrees.
  • Step 3: Know that consecutive angles in a parallelogram are supplementary, meaning they add up to 180 degrees.
  • Step 4: To find the other two angles, subtract 70 degrees from 180 degrees: 180 - 70 = 110 degrees.
  • Step 5: Therefore, the two remaining angles are both 110 degrees.
  • Properties of Parallelograms – In a parallelogram, opposite angles are equal, and consecutive angles are supplementary (sum to 180 degrees).
