Right angles are straight lines, and straight lines are right angles, right?

A right angle consists of two rays. It is the angle formed by light rotation 180 degrees instead of a straight line. It has a vertex, but a straight line has no vertex. A right angle is the same as a straight line in a graph, but one is an angle and the other is a straight line. Don't confuse them.

differentiate

1. Flat angle is an angle, which conforms to the definition of angle; And straight lines are "lines";

2. The flat angle can be measured, 1 flat angle = 180 degrees; Straight lines are unmeasurable;

The most obvious difference is that a right angle has a vertex and two sides, while a straight line does not.

Because both sides of a right angle and its vertex are on the same straight line, we can see a "special straight line" from the shape, so for the convenience of studying problems, we sometimes regard the right angle as a straight line. Take a point on a straight line, which divides the straight line into two rays with a common endpoint, and then we can regard this straight line as a right angle. Bottom line: For the need of research, straight lines and flat angles can be transformed into each other.
