Can 5 11 4 be the sides of a triangle?

A triangle has sides of lengths 4 3 and 5 is it a right triangle?

Yes, it is.

Do these three sides make a right triangle 6 5 and 11?

No

How do you find the scale factor if they give you the perimeter ratio?

Let's get at the idea by working backward. Suppose we know the scale factor; what will the ratio of perimeters be? For instance, suppose we have two triangles; one has sides of 3, 4, and 5 inches; the other has sides of 33, 44, and 55 inches. The scalefactor is 11: you multiply each side length of the first triangle to get the corresponding side length of the second triangle. Now look at the perimeters. The perimeter of the first triangle is 3+4+5 = 12 inches. The perimeter of the second triangle is 33+44+55 = 132 inches. The ratio of perimeters is 132/12 = 11. Do you notice that it's the same as the scale factor? This will always be true! Here is why. We can write the sides of the second triangle as 3*11, 4*11, and 5*11. Then the perimeter is 3*11 + 4*11 + 5*11 = (3 + 4 + 5)*11 using the distributive property. To find the ratio of perimeters, divide this by the perimeter of the first triangle: (3+4+5)*11 ---------- = 11 3+4+5 Let's continue and think about the ratio of areas. The triangles I chose happen to be right triangles (do you know how to show this?) so the area is half the product of the two shorter sides. Thus the area of the first triangle is (3*4)/2 = 6 square inches. The area of the second triangle is (33*44)/6 = 726 square inches. The ratio of areas is 726/6 = 121. This ratio happens to be 11 squared. It will always be true that the ratio of areas is the square of the scale factor. Again, we can see why this is true. Writing the sides of the second triangle as 3*11 and 4*11, the area is 3*11 * 4*11 = (3*4)*(11*11) Divide this by the area of the first triangle to find the ratio of areas: (3*4)*(11*11) ------------- = 11*11 = 11^2 3*4 Do you see how it works now? What is the answer to your problem?

If the two adjacent sides of a triangle are 3' and 4' what is the length of the hypotenuse?

If the two adjacent sides of a triangle are 3' and 4', the hypotenuse is: 5'

What shape does not have exactly 4 sides?

For example, one that has 3 sides (a triangle), one that has 5 sides (a pentagon), etc.

If the sides of a right angle triangle are in APthen these sides are in ratio of?

3 : 4 : 5

What is the perimeter of a triangle with sides of 3 in 3 in and 5 in?

3 + 3 + 5 = 11 inches

Would the following set of sides build a triangle 4 4 5?

Yes. If the sum of the length of the two smaller sides are greater than the length of the larger side and none of the lengths of any of the sides equals 0, then it is a triangle. It is not, however, an equilateral triangle or right triangle (that would be 5, 4, 3), though it is an isosceles triangle.

Is ir possible to construct a triangle with sides 4 5 and 9?

4+9>5 5+9>4 4+5 is not greater than 9 No, since it doesn't comply with the Triangle Inequality Theorem (the sum of the lengths of any two sides of a triangle is greater than the length of the third side)

How do you construct a 3 4 5 triangle Read?

It will be a right angled triangle with sides of 3 and 4 units with an hypotenuse of 5 units in length.

What could be the measure of the sides of a right triangle?

3, 4 and 5

A triangle has sides that measure 3 cm 4 cm and 5 cm. What type of triangle is it?

This is a right angle triangle.
