Angles Gcse Maths Steps Examples Worksheet Adding the angles together, we can form the expression. 70 90 = 160.70 90 = 160. 2 subtract the angle sum from 180 o180o. as the sum of angles on a straight line total 180 o, 180o, 180 − 160 = 20.180 −160 = 20. 3 form and solve the equation. here we have no equation to solve as the missing angle is 20 o.20o. The name of the angle on the left is ∠abc or ∠cba. there are generally 4 types of angles you will come across in gcse maths: acute angles – an acute angle is an angle that is less than 90°: obtuse angles – an obtuse angle is an angle greater than 90° but less than 180°: reflex angles – a reflex angle is greater than 180° but less.
Maths Gcse Worksheet Using Angle Facts By Tristanjones Teaching Edexcel gcse mathematics (linear) – 1ma0 angles materials required for examination items included with question papers ruler graduated in centimetres and nil millimetres, protractor, compasses, pen, hb pencil, eraser. tracing paper may be used. instructions use black ink or ball point pen. Angle, right, straight line, point, full turn, vertically, opposite, basic, facts, triangle, quadrilateral. Show step. co interior angles add up to 180o 180o. here 180−110=70o 180 − 110 = 70o. state the alternate angle, co interior angle or corresponding angle fact to find a missing angle in the diagram. show step. θ θ is corresponding to 70 35 70 35 so θ=70 35=105o θ = 70 35 = 105o. This means we will need multiple steps. firstly, we will use the fact that angles on a straight line add to 180 degrees. specifically, \angle efc and \angle cfg add to make 180\degree. which means we can do the following: \angle cfg = 180\degree 32\degree = 148\degree. now, looking at the diagram we can see that angle \angle cfg and the.

Interior and exterior angles example questions. question 1: the shape below is a regular pentagon. work out the size of the interior angle, x. [2 marks] level 4 5 gcse ks3 aqa edexcel ocr wjec edexcel igcse. show answer. question 2: the shape below is a regular octagon. work out the size of the interior angle, x. Calculate how many sides the polygon has. step 1: work out the value of the exterior angle by extending the side of the polygon and using the fact that angles on a line add up to . step 2: use the fact that the exterior angles 45 add up to 360o to find the ×. so, the polygon has 8 sides and is therefore. an octagon.
