The perimeter of a triangle is simply the sum of the lengths of its three sides. Knowing that it is right angles (or not) is rarely of help.

How do you find the hypotenuse of a non right triangle?
By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.
How many pairs of perpendicular lines does an isosceles triangle have?
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
Is a triangle supplementary or complementary?
In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. When two angles add to 90°, we say they "Complement" each other.
Can you show how a right triangle has one line of symmetry?
the only way for a right triangle to have a line of symmetry, is if the legs of the triangle are congruent. Or you can show that both non-right angles are congruent (45 degrees). you may also prove that the altitude of the triangle bisects the hypotenuse or that it equals 1/2 of the hypotenuse.
Can trig functions work on non-right triangles?
Yes. Look up the law of sines and the law of cosines as examples. there are also formulas that can find out the area of a non-right triangle.
How do you work out the perimeter of a non right-angled triangle?
-- Measure or calculate the length of each of its 3 sides. -- Add the lengths of its 3 sides. -- The sum is the perimeter of the triangle.
How do you find the hypotenuse of a non right triangle?
By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.
Calculate a side of a triangle?
Pythagoras's' theorem or "got an want" on a right angled triangle but use sine rule on a non right angled triangle !! ..
How many pairs of perpendicular lines does an isosceles triangle have?
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
Can you show me a non right angled scalene triangle?
yes, just type scalene triangle in Google Image search.
What shape has one acute and three obtuse angle?
arrowhead :)
A scalene triangle cannot contain a right angle?
False. The basic Pythagorean triangle's sides are in the ratio 3:4:5. The only non-scalene right-angled triangle which comes to mind is the isosceles with two 45o angles. Law: Every right-angled triangle is scalene unless it contains an angle of 45o.
How do you find an angle within a non-right angled triangle when only given one side length?
You cannot find any angle, or either of the other two sides, in a non-right triangle, when given only one side.
How was sine cosine and tangent created?
They are all ratios for triangles found by dividing one side of a triangle by the others. Ex: sine=opposite side/hypotenuse. *** This is so for a right-angled triangle. Non-right-angle triangle dimensions can be calculated by trigonometry but require more complicated derived formulae.
Make a right angled isosceles triangle This is a triangle with a right angle and two equal anles that are not right angles What is the size of these non right angles?
45 degrees. they have to be the same angle, because they are opposite equal lengths, and when added together they must equal 90, so as to make the total of the angles 180.
What is a non-isosceles right triangle?
A non-isosceles right triangle is a right triangle (one angle is 90 degrees) and all sides are of different lengths. (therefore causing all angles to be different too). This type of triangle is known as a right scalene
What are the formula of trigonometry till class 10th?
Different topics are taught in different countries at various ages.I expect that the main formulae will be the definitions of sine and cosine ratios in the context of right angled triangles, the tangent ratio - either from a right angled triangle or in as derived from sine and cosine. There will also be the squared ratios identity. In year 10 or 11, pupils will learn the sine and cosine rules for general (non-right angled) triangles, and the area of a segment of a circle.
