Angles Worksheets and Answers
Angles Practice Worksheets
Angles worksheet practice questions and answers for GCSE maths at foundation and higher. 12 angles worksheets covering corresponding angles, alternate angles and estimating angles. Angles worksheet 1 contains questions on estimating angles. Angles worksheet 2 contains questions on measuring and estimating angles and angles worksheet 3 uses angle notation. Angles worksheet 4 through to angles worksheet 12 contains questions on angles on parallel lines, angles in triangles and angle on straight lines.
Students will be able to draw angles with a protractor. Looking at the protractor below we see that angles between 0 degrees and 180 degrees can be measured. Angles larger than 180 degrees are called reflex angles. To measure reflex angles we use a full sized protractor.
Types of Angles
Types of angles worksheet showing acute angles, obtuse angles, right angles and reflex angles.
Angles Question and Answer 1
Angles Question and Answer 2
Skills required to access the angles question below include: angles on a straight line equal 180 degrees and angles about a point equal to 360o. The unmarked missing angle is 37o because 180o - 143o equals 37o. The missing angle marked ? must be 53o because 90o - 37o = 53o.
What is a Right Angle?
Angles worksheet asking students to correctly identify the right-angle. A right angle has 90 degrees. A small box is used to identify right angles. Angles less than 90 degrees are called acute angles. Angles greater than 90 degrees and less than 180 degrees are obtuse angles.
Angles On A Straight Line
How to Find Angles on Parallel Lines
Angles on parallel lines are the same in different places. "Z angles" and "F angles" are also called Alternate Angles and Corresponding Angles. Alternate angles are the same when between parallel lines, and the angles form a Z shape. Corresponding angles are the same when between parallel lines, and the angles form an F shape.
Angles Question and Answer 3
Skills required to access the angles question below include: similar angles on parallel lines are corresponding angles. The missing angle is 34o because it is a corresponding angle between parallel lines.
Angles Question and Answer 4
Skills required to access the angles question below include: similar angles on parallel lines are alternate angles and opposite angles are equal. The missing angle is 66o because it is a an opposite angle. The second unknown angle is also 66o because it is an alternate angle (F angle).
