Step 1: Provide the reason for statement 2.1.1. The diagram shows two angles, x and 40^, that lie on a straight line. Angles on a straight line sum to 180^. x + 40^ = 180^ Reason 2.1.1: Angles on a straight line. Step 2: Provide the reason for statement 2.1.2. The diagram shows four angles, a, b, c, d, around a central point where two lines intersect. The sum of angles around a point is 360^. a + b + c + d = 360^ Reason 2.1.2: Angles around a point (or angles in a revolution). Step 3: Provide the reason for statement 2.1.3. The diagram shows two parallel lines, PQ and RS, intersected by a transversal. Angles e and f are interior angles on the same side of the transversal. These are also known as co-interior angles. Co-interior angles between parallel lines are supplementary (add up to 180^). e + f = 180^ Reason 2.1.3: Co-interior angles are supplementary (PQ || RS). Step 4: Provide the reason for statement 2.1.4. The diagram shows two parallel lines, PQ and RS, intersected by a transversal. Angles e and g are alternate interior angles. Alternate interior angles between parallel lines are equal. e = g Reason 2.1.4: Alternate interior angles are equal (PQ || RS). Step 5: Provide the reason for statement 2.1.5. The diagram shows two parallel lines, RS and TU, intersected by a transversal. Angles i and g are corresponding angles. Corresponding angles between parallel lines are equal. i = g Reason 2.1.5: Corresponding angles are equal (RS || TU). Last free one today — make it count tomorrow, or type /upgrade for unlimited.
