## Perpendicular

To make a perpendicular angle you first make a line with the points ABC. Next select the point through center circle tool and let go in-between points C and B. This makes point D. Then select the point tool and mark the intersection circle C in-between points C and A. This makes point E. Next use the point through center point tool and place on point D and release in-between points C and E to create point F. Use the compass tool and select points F and D to get the same radius then place this new circle on point E. Select the point tool and mark the intersection of the two circles, points G and H. Now select the line segment tool and connect points G and H together to find the intersection. By using the angle tool you know that all angles add up to 90 degrees.
