Add a point to the line () and label the line CD. ﻿d. Use the line tool to create a transversal that ﻿ ﻿crosses AB and CD. ﻿e. Use the point tool to put a point at each ﻿ ﻿intersection of the lines. 2. Use the angle measuring tool () to measure all 8 ﻿ ﻿angles created by these lines. ﻿(if the angle measure is over 180, click the points in the opposite direction.) ﻿
