Using the sine rule in trigonometry its other sides are 13.62cm and 16.35cm both rounded to two decimal places therefore it follows that the perimeter of the triangle is 14.5cm+13.62xm+16.35cm = 44.47cm

An isosceles right angle triangle

Yes. A triangle can be classified as: For angles 1. If a triangle has at least 1 angle that has an angle measure of more than 90 degrees, it can be called an obtuse triangle 2. If a triangle has 3 angles that are less than 90 degrees, it's a acute triangle. 3. If a triangle has an angle that has an angle measure of 90 degrees, it can be called and right triangle For sides: 1. All equal sides= equilateral. 2. 2 equal sides= Isosceles 3. No equal sides= scalene

If you mean sides of 6, 8 and 10 inches then it is a right angle with a perimeter of 24 inches.

Its longest side of 162cm is opposite to its biggest angle which is 94.54 degrees and by using the sine rule its other sides are 98.34cm and 121.49cm. Therefore perimeter of the triangle is: 162+98.34+121.49 = 381.83cm

Using the trigonometry sine rule the other sides of the triangle are 16.35cm and 13.62cm so it follows that its perimeter is 14.5+16.35+13.62 = 44.47cm

A triangle with two congruent sides is isosceles. A triangle with an angle of 104 degrees is obtuse. So you would have an obtuse isosceles triangle.

Using the sine rule in trigonometry its other sides are 13.62cm and 16.35cm both rounded to two decimal places therefore it follows that the perimeter of the triangle is 14.5cm+13.62xm+16.35cm = 44.47cm

add all of the sides together

a scalene triangle

the triangle is called right handed triangle

An isosceles right angle triangle

Not necessarily. A triangle with two equal sides is called an isoceles triangle. A right triangle has one angle that measures 90 degrees.

The 3rd angle must be 52 degrees and so by using the sine rule in trigonometry its other sides are 16.35cm and 13.62cm both rounded to two decimal places. Therefore the perimeter of the triangle is: 14.5+16.35+13.62 = 44.47cm

A triangle has 3 sides and 3 inside angle that add up to 180 degrees

A triangle has no parallel sides but a right angle triangle has perpendicular sides that meet at 90 degrees.
