No because the sum of the smaller sides must be greater than the longest side
Yes
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
Area is 36cm2
the perimeter is 36 and the area is 144
Yes
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.
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.
If a right triangle has sides of 16Cm and 12Cm, the hypotenuse is: 20 cm
The area of a 12cm by 5cm right-angled triangle is: 42 cm2
30 square cm because it's a right angle triangle
A right triangle with a hypotenuse of 12cm and an angle 30 degrees has an opposite angle of: 60 degrees.
Isosceles
this is 5cm (:
22cm
If it is an equilateral triangle with 3 equal sides of 4m then its perimeter is 12cm
If it is an equilateral triangle with 3 equal sides of 4cm then its perimeter is 12cm
