If a right triangle has sides of 16Cm and 12Cm, the hypotenuse is: 20 cm
30 square cm because it's a right angle triangle
6 * sqrt(3) cm. This should be trivially obvious from the Pythagorean theorem.
A right angle triangle fits the dimensions given
No because the sum of the smaller sides must be greater than the longest side
If a right triangle has sides of 16Cm and 12Cm, the hypotenuse is: 20 cm
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
The area of a 12cm by 5cm right-angled triangle is: 42 cm2
Isosceles
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
22cm
30 square cm because it's a right angle triangle
I cut out the lengths to have a visual look at the problem and the answer is NO you cannot arrange 5cm, 12cm, and 19cm into a triangle. Even straightening out the lengths of 5cm and 12cm into a 180 degree angle will not measure out to the 19cm. You cannot have a side that is more than the length of the other two sides combined in a triangle.
It will be a right angle triangle with a base of 3cm, a height of 4cm and a hypotenuse of 5cm
A right triangle with a hypotenuse of 12cm and an angle 30 degrees has an opposite angle of: 60 degrees.
If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm
52 + 122 = 25 + 144 = 169 = 132 This calculation confirms that the three sides of length 5, 12 and 13 cm form a right angled triangle with the side of length 13cm being the hypotenuse.
