| + | === Objectives === |
| + | To verify vertically opposite angles are equal |
| + | |
| + | === Estimated Time === |
| + | 20 minutes |
| + | |
| + | === Prerequisites/Instructions, prior preparations, if any === |
| + | Knowledge about point, line, angle |
| + | |
| + | === Materials/ Resources needed === |
| + | Digital: Click here to [[:File:Intersection of two lines.ggb|open]] the file |
| + | |
| + | Non-digital: Paper, pencil, ruler, compass, protractor |
| + | |
| + | ===Process (How to do the activity) === |
| + | {{Geogebra|haaj2yr5}}'''Procedure :''' |
| + | # What are intersecting lines? |
| + | # Identify two lines cross each other in a plane i.e. lines 'g' and 'f' intersect at point 'A' |
| + | # Identify intersecting lines (two or more) meet only at one point always and also can cross each other at common vertex (which is the point of intersection). |
| + | # Identify the angles formed at common vertex 'A' |
| + | # Identify two pairs of opposite angles |
| + | # What is the vertically opposite angle?how many pair of vertically opposite angles are formed? |
| + | # Identify and measure vertically opposite angles?What is your conclusion? |
| + | # Can vertically opposite angles be adjacent? |
| + | # How many pairs of adjacent angles are formed? |
| + | # Idenify and measure adjacent angles?What is your conclusion? |
| + | === Evaluation at the end of the activity === |
| + | # Can two lines cross at two points? |
| + | # If out of two angles of linear pair one is 60°, then what is the measure of other angle? |
| + | # If two angles are vertically opposite angles, where the measure of one of the angles is 30°, then what is the measure of other angle? |
