How do you rotate a polygon 90 degrees counterclockwise about the origin?
{1 0} {0 -1}
A triangle with one angle over 90 degrees?
A triangle with one angle over 90 degrees is an obtuse triangle.
A triangle that has one angle greater than 90 degrees?
this is called an obtuse triangle the triangle that has one angle 90 degrees is called a right traingle a triangle that has 3 angles less than 90 degrees is called an acute triangle
Can a right triangle have two angles that measure 90 degrees?
Yes a 90- 60-30 triangle for example because there are 180 degrees in a triangle.
How do you rotate a figure 90 degrees counterclockwise?
The formula is (x,y) -> (y,-x). Verbal : switch the coordinates ; then change the sign of the new x coordinate. Example : (2,1) -> (1,-2)
How do you rotate a triangle by 90 degrees clockwise?
rotate it 90 degrees
How do you rotate a polygon 90 degrees counterclockwise about the origin?
{1 0} {0 -1}
Suppose a figure is located in quadrant 1. Which of the following will result in an image that is located in quadrant 3?
A) Rotate 360 degrees counterclockwise, then shift 1 unit up. B) Rotate 180 degrees counterclockwise, then shift 1 unit down. C)Rotate 90 degrees counterclockwise, then shift 1 unit up. D) Rotate 270 degrees counterclockwise, then shift 1 unit down.
How many degrees has triangle ABC been rotated counterclockwise about the origin?
180 degrees.
How do you rotate a triangle 90 degrees about a point?
Trace the triangle on tracing paper, flip the tracing paper so the drawn triangle is touching the paper and then put your pencil on the point (with the tracing paper underneath) that you need to rotate from. Then rotate the paper 90 degrees and draw over the triangle you drew on the tracing paper to stamp it down.
Will the sides of the triangle change if rotate a figure 90 degrees clockwise about origin?
No, only their positions will change.
How do you know when a triangle is 90 degrees?
we know that a triangle is 90 degrees by measuring its length or it can be known as right triangle which measures 90 degrees.
What is 90 degrees counterclockwise?
Clockwise means turning to your right, counterclockwise is to the left.
If the angles in a triangle are 30 degrees 60 degrees and 90 degrees is called what type of triangle is it?
A right angles triangle, as one of the angles in the triangle is 90 degrees.
Rotate do you rotate a figure 270 degrees counterclockwise?
270 degrees is 3/4 of the way around the circle. Ir is the same as rotating it 90 degrees (1/4) of the way clockwise. Turn it so anything that was pointing straight up would be pointing to the right.
What are the angle classifications of a triangle?
The question "What are the classifications of a triangle" is answered elsewhere. The angles in a triangle can be either an obtuse >90 degrees, an acute <90 degrees, or a rectal = 90 degrees
A right triangle is a triangle that has how degrees?
It has 180 degrees, but one angle of the triangle has to be 90 degrees
