Missing Angles Our learning objectives today To calculate missing angles on a straight line, around a point and in a triangle. To use a protractor to draw and measure acute and obtuse angles …

**3 Angle Geometry MEP Pupil Text 3 CIMT**

Two or more angles on a straight line add up to 180 °. In the diagram above, the circle to the left is split into three sectors the angles of the green and white sectors are both 90°, adding up to 180°.... Unless you have any other information (other angles, line lengths, heights of perpendiculars etc.) which might help you to deduce it then you will need to either measure it directly using a protractor or indirectly using a ruler, and possibly a pair of compasses, to provide you with enough information to deduce it.

These lines are parallel, because a pair of Corresponding Angles are equal. These lines are not parallel, because a pair of Consecutive Interior Angles do not add up to 180° (81° + 101° =182°) These lines are parallel, because a pair of Alternate Interior Angles are equal... Parallel lines which are intersected by an oblique line give rise to sets of equal angles. The two angles marked in diagram (a) are equal. They are corresponding angles …

See below, for example, where A, B and C lie on a straight line, and a triangulation is attempted from C. At first sight the interior angles may appear to be the sum of four triangles. But at closer inspection it will be evident that there is a straight angle at B (equivalent to the interior angles of a fifth triangle).... Divide the yearly amount of depreciation by the time period the cash flow statement is applicable for. For example, where a cash flow statement is prepared for each quarter, the yearly depreciated amount must be divided by four to reflect the quarterly depreciated amount.

- Angle ADB = 180-38-38 = 104° because angles in a triangle add up to 180° Therefore x = 360°-(104° x 2) = 152° because angles around a point add up to 360° *The reasons are not needed for the marks, but it …
- Watch video · We're given a bunch of lines here that intersect in all different ways and form triangles. And what I want to do in this video, we've been given the measures of some of the angles, this angle, that angle, and that angle.
- For alternate angles to exist we need a minimum of one pair of parallel lines and one transverse line. Alternate angles are equal. a = b b a a = b b a Other types of angles to be considered are corresponding anglesco-interior angles, ,
