In a triangle, two equal angles are 55°. Find the third angle., A) 70° , B) 65°, C) 60°, D) 75°, One corresponding angle is 80° in parallel lines. Find the other corresponding angle., A) 70° , B) 80°, C) 60°, D) 90°, One angle of the interior angles is 110°. Find the other angle., 80° , B) 70°, C) 55°, D) 90°, Co-interior angles of parallel lines add up to…, A) 90°, B) 180° , C) 270°, D) 360°, Angles at a point always add up to 360°, True, False, Angles on a straight line add up to 360°, True, False, Corresponding angles are found by looking to an 'F' shape, True, they are found by looking an 'F' shape, False, they are not found by looking for the 'F' shape, Alternate angles are found by looking to a 'Z' shape, False, they are found by looking by to an 'F' shape, True, they are found by looking for a 'Z' shape, If an angle in a triangle is 90°, the other two angles are always....., 45° and 85°, 45° and 45°, 60° and 60°, 60° and 70°, Choose the correct answer....., Angle x is 121° ( vertically opposite angles are equal), 360°-121°=239° (angles at a point add up to 360180°-121°=59° (angles on a straight line add up to 18), 180°-121°=59° (angles on a straight line add up to 180°), 180°-121°=59° (interior angles add up to 180°), Choose the correct answer....., 123° (vertically opposite angles ), 137° (vertically opposite angles), 180°-123°= 57° (angles on a straight line), 360°-137°-123°=100° (angles at a point), There are two interior angles. One of them is 70°. The other one is...?, 70° (interior angles are equal), 110° (interior angles add up to 180°), 290° (interior angles add up to 360°).
