A 3-sided shape with one of the angles appearing like the corner of a square.
A right angled triangle has a base horizontal line with a start and end point (A,B).
A Perpendicular line rises from either of the end points perpendicular, or at a 90 degree angle from the base line. The third point )at the top of the perpendicular line) is called 'C'.
If the line was drawn from 'A', then join 'C' and 'B'.
You have a right angled triangle.
Well, honey, the orthocenter of a right triangle is where all three altitudes intersect. In the case of a right triangle, the orthocenter coincides with one of the vertices, specifically the right angle vertex. So, grab your ruler and draw those altitudes to find that sassy orthocenter right at the corner of the right angle.
Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
180, just like every other triangle. the actual right angle is 90 and the other to angles equal 90
well you know what a right angle looks like? well its not half of that. however half of a right angle is 45 degrees so close to 42
-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]
It will look like a right angle triangle with a 90 degree angle and two 45 degree angles and will have one line of symmetry
It is called an obtuce angle because it looks like this right?: -------------------------_------------------------ or a right angle if it looks like this: ! ! ! ! ! ! ! ---------------------------------
If the a vertex forms a right angle which looks like this: 'L' that's is a right angle...sooo if there's a slope connecting the top of the L to the bottom of the L then it would be a right triangle....so in conclusion....as long as there's a vertex that forms a capital L somewhere then....it's a right triangle :)
It looks like a corner. 90 degrees. also a right angle
A 90 degree angle, also known as a right angle, looks like the corner of a square or rectangle. The two lines that form the 90 degree angle are perpendicular to one another.
The right angle of a right-angle triangle, like all right angles, is 90 degrees or one quarter of 360 (a full circle). All the angles of any triangle will add up to 180 degrees.
It is any triangle - one with no special characteristic - like a right angle, or two equal sides, etc.
a triangle w/ an angle perpendicular like this l_
it is a right angle triangle
no right angle with only one angle is obtuse
It looks like a right angle a right angle wich is 90 degrees
Because the Bottom left corner makes a 90 degree angle like this |_ and a 90 degree angle is called a Right angle thus the name Right angled Triangle
