Find all the non-flattened corners formed by the intersection of two straight lines if one of them is 29 degrees.

1. Since at the intersection of two straight lines two pairs of vertical angles are formed, then the second angle will also be equal to 29˚.

2. Find the second pair of vertical angles 180˚ – 29˚ = 151˚, that is, each angle of the second pair is equal to 151˚.

Answer: the undeveloped angles formed at the intersection of two straight lines are equal to 29˚, 151˚, 29˚, 151˚.
