Questions & Step-by-Step Solutions

If two angles are equal and their sum is 180 degrees, what type of angles are they?
  • Step 1: Understand that we have two angles that are equal.
  • Step 2: Let’s call each angle 'x'. Since they are equal, we can say the first angle is x and the second angle is also x.
  • Step 3: According to the question, the sum of these two angles is 180 degrees. So we can write the equation: x + x = 180.
  • Step 4: Simplify the equation: 2x = 180.
  • Step 5: To find the value of x, divide both sides of the equation by 2: x = 180 / 2.
  • Step 6: Calculate the value: x = 90 degrees.
  • Step 7: Since both angles are equal and each measures 90 degrees, we can conclude that they are right angles.
