Vertical Angles solving for x

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

If two angles are vertical angles, what can we say about their measures?

Back

The measures of vertical angles are equal.

Front

Solve for x: If m∠1 = x and m∠2 = 3x, what is x if m∠1 and m∠2 are vertical angles?

Back

x = 0° (not possible in this context, but illustrates the concept of equality).

Front

Find the missing angle: If m∠A = 70°, what is m∠B if A and B are vertical angles?

Back

m∠B = 70°.

Front

What is the relationship between adjacent angles formed by intersecting lines?

Back

Adjacent angles are supplementary, meaning their measures add up to 180°.

Front

If m∠1 = 45°, what is m∠3 if ∠1 and ∠3 are vertical angles?

Back

m∠3 = 45°.

Front

Solve for x: If m∠A = 2x and m∠B = 3x, and A and B are vertical angles, what is x?

Back

x = 0° (not possible in this context, but illustrates the concept of equality).

Front

What is the sum of the measures of two vertical angles?

Back

The sum of the measures of two vertical angles is always equal to 2 times the measure of one of the angles.

Front

If m∠1 = 60°, what is m∠2 if ∠1 and ∠2 are vertical angles?

Back

m∠2 = 60°.

Front

Find x: If m∠1 = 3x and m∠2 = 5x, and they are vertical angles, what is x?

Back

x = 0° (not possible in this context, but illustrates the concept of equality).
