Lines and angles. A line is an infinite number of points between two end points. Where two lines meet or cross, they form an angle. An angle is an amount of rotation. It is measured in degrees. Types of angles. Name of angle. Example.

Question 1: Write down if each angle below is acute, obtuse or reAlex. Question 2: Estimate the size of each angle in question 1. Question 4: Measure the size of each angle you have drawn in question 3. Measure the sizes of angles x and y.
Exercise 1. Find the missing angles and give reasons for your answers. Exercise 2. Set up an equation to find x in each of the following. Reasons MUST be clearly stated. Parallel Lines with more complicated diagrams. Exercise 3. 3.1. Find the values of a to g, giving reasons in each case.
Angles Worksheets. Angles worksheets promote a better understanding of the various types of angles and how to differentiate among them. Angles can be broadly classified into five types - acute, obtuse, right, reflex, straight, and full rotation.
Classify the angles in the following exercises as acute, obtuse, right, or straight.
The lesson lists five types of angles: acute (less than 90°); right (exactly 90°); obtuse (greater than 90° but less than 180°); straight (exactly 180°); and reflex (greater than 180°). The lesson also provides some mnemonic devices to help students remember each type of angle.
