## Is a rotation of 180 degrees the same as a reflection?

The 180 degree rotation acts like both a horizontal (y-axis) and vertical (x-axis) reflection in one action.

The reflection is the same as rotating the figure 180 degrees..

## What are the rules for clockwise rotations?

Terms in this set (9)(-y, x) 90 degree rotation counterclockwise around the origin.(y, -x) 90 degree rotation clockwise about the origin.(-x, -y) 180 degree rotation clockwise and counterclockwise about the origin.(-y, x) 270 degree rotation clockwise about the origin.(y, -x) … (x, -y) … (-x, y) … (y, x)More items…

## What does 180 degrees look like?

Straight Angles An angle with a measure of 180 degrees is called a straight angle. It looks just like a line.

## What does 90 degrees look like?

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. … The term is a calque of Latin angulus rectus; here rectus means “upright”, referring to the vertical perpendicular to a horizontal base line.

## How do you rotate a point?

A point (a, b) rotated around a point (x, y) 90 degrees will transform to point (-(b-y) + x, (a-x) + y). A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a – x) + x, -(b – y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b – y + x, -(a – x) + y).

## What is the formula for a 90 degree clockwise rotation?

180 degrees is (-a, -b) and 360 is (a, b). 360 degrees doesn’t change since it is a full rotation or a full circle. Also this is for a counterclockwise rotation. If you want to do a clockwise rotation follow these formulas: 90 = (b, -a); 180 = (-a, -b); 270 = (-b, a); 360 = (a, b).

## Is a 90 degree rotation clockwise or counterclockwise?

Since the rotation is 90 degrees, you will rotating the point in a clockwise direction.

## What happens when you rotate a point 90 degrees clockwise?

Rotation of point through 90° about the origin in clockwise direction when point M (h, k) is rotated about the origin O through 90° in clockwise direction. … The new position of point M (h, k) will become M’ (k, -h).
