Right angles are created by perpendicular lines. You first have to find the slopes of the lines. You know lines are perpendicular when the slopes are negative reciprocals. For example: If you find the slope of Line AB to be -2, in order for the lines to form right angles, the following line would have to be 1/2. So getting back to your question, calculate the slopes and show they are negative reciprocals. Hope I Helped!

How is geometry used in lacrosse?
Lacrosse uses geometry when shooting and passing. Having the right angle on the stick will help control the ball and the where it goes.
If a parallelogram has a right angle is it a rectangle?
No because it could be an irregular quadrilateral that includes a right angle. A rectangle has four right angles.Yes, a parallelogram with a right angle is always a rectangle. In fact, in my geometry book, some 55 years ago, such was the definition of rectangle.A parallelogram with one right angle will always have four right angles.It is true that you can draw an irregular quadrilateral with a right angle which is not a rectangle but the figure will not be a parallelogram.
A shape with no right angle with a reflex angle four sides two parallel sides and have the same lenght?
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
What is a 99 degree angle called?
A 99-degree angle is called an obtuse angle. In geometry, an obtuse angle is an angle that measures between 90 and 180 degrees. It is larger than a right angle (90 degrees) but smaller than a straight angle (180 degrees).
Does a right triangle have three right angles?
Not in traditional, 2 dimensional, euclidean geometry, because a triangles angles always equal 180º .However, there is a branch of Geometry that deals with a coordinate system on a sphere, instead of a plane, and in spherical geometry a triangle with three right angles is very much possible. Consider, for example, the triangle bounded by the Prime Meridian, 90o west longitude, and the equator.
What is a right angle in geometry?
It is an angle that is 90 degrees.
What are the three angles?
Acute angle, right angle and obtuse angle
How do you prove a right angle triangle?
You cannot prove "a right angle triangle". You may or may not be able to prove statements about right angled triangles but that will depend on the particular statement.
Graphs for how can you use coordinate geometry in your daily life?
If Your An Pilot Then You Need To Know How To Get To The right Spot.
How do you prove a square has one right angle?
it doesnt
What is formed by two number lines that intersect at a right angle?
a coordinate plane
Is it true that an obtuse triangle can have a right angle?
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.
How is 90 an important number in geometry?
Because 90 degrees is a right angle
How do we use coordinate geometry in daily life?
if you are traveling you will need to know the coordinates to make sure you are in the right place
What is a acute angle in geometry?
acute angle IS SMALLER tHAN a Right Angle so it is Graeater than 0degree but Smaller than 90degree
What is a hypotonuse?
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.
If one were trying to prove that an angle is right by indirect proof what should the initial assumption be?
The initial assumption is "that it is NOT a right angle"
