Determine whether the lines are parallel or perpendicular or both or neither.

Use the Vertical Angles Congruence Theorem to find the measure of each angle in the diagram at the right.

For such questions, we should know properties of vertical angles. We should know the rules of algebra to solve the equations. The alternate way to solve the question will be using supplementary angles. When two angles intersect, the sum of adjacent angles is 180°.

Can you find the pattern?
3, 5, 1, 3, -1, ___, ___, ____.

For such questions, we should find the relation between the consecutive numbers or if necessary alternate numbers. Another way of solving the above sum is to find the difference between alternate terms. There is constant difference between alternate terms.

Sketch the next figure in the pattern.

For such questions, we have to find the relation between two consecutive shapes. Using the information, we can complete the rest of the pattern.
