Consider the following figure.

Three rays start from a single point and form 3 angles.

• The first ray starts at pointBand goes vertically up through pointA.
• The second ray starts at pointBand goes up and to the right through pointD.
• The third ray starts at pointBand goes horizontally to the right through pointC.
• The angle to the right of the first ray and above the second ray is labeled 1.
• The angle below the second ray and above the third ray is labeled 2.
• The angle starting clockwise at the first ray and ending at the third ray is marked with a right angle symbol.

Describe the relationship between the angles. (Select all that apply.)
