Question 4

When using a CAD system, specific points in geometry may be located using the GRID function.

Question 5

The sum of the squares of the shorter legs of a right triangle is equal to the square of the hypotenuse.

Question 6

Two circles having different size radii but having the same center point are said to be eccentric circles.

Question 7

When using an ellipse template to draw ellipses, it is necessary to select a template that approximates the ellipse angle.

Question 8

By correctly placing standard drawing triangles, you are able to draw angles at 10° increments.

Question 9

A straight line that intersects a circle at only one point, regardless of its length, creates a point of tangency.

Question 10

A straight line drawn as a perpendicular bisector of another straight line will form two 90-degree angles.

Question 11

A triangle having all angles equal describes an ___________________ triangle.

Question 12
