Q:
# What is the apex of a curve?

A:

**The apex of a curve is its highest point.** Geometric use of the term "apex" generally refers to solids or to shapes with corners such as triangles. In autoracing and other motor sports, the apex is the point on the track that is closest to the inside of a curve.

An apex is a special type of vertex. A vertex is generally a corner of a figure, a common endpoint for two or more sides. In the case of curves, which do not have corners, a vertex is the sharpest point of the curve. Usually, this is some maximum or minimum value along the vertical axis. An apex is the highest vertex. In motorsports, the apex of a curve is a key concept for finding the best point on a track to start a turn in order to get the best racing time.

Q:
## What is the midline theorem?

A:The midline theorem, formally known as Varignon's theorem, states that a parallelogram is formed when the midpoints of the sides of any convex quadrilateral are connected in order. The area of the Varignon parallelogram is half of the original quadrilateral.

Q:
## Why can't a triangle have more than one obtuse angle?

A:An obtuse angle is more than 90 degrees. The three angles within any triangle always equal exactly 180 degrees. If two angles are obtuse — even if they are both only 91 degrees — they add up to more than 180 degrees. Therefore, it is impossible for more than one angle in a triangle to be greater than 90 degrees.
