Which dimensions can create only one unique triangle?
A.Three angles measuring 25,65,and 90
B.Three angles measuring 50,50,and 50
C.Three sides measuring 5 in,12 in,and 14 in
D.Three sides measuring 4 ft,8 ft,and 14 ft

Respuesta :

Verify each case

case A. Three angles measuring 25,65,and 90

sum of a internal angles=25+65+90-----> 180° is ok

That dimensions can create infinity similar triangles

case B. Three angles measuring 50,50,and 50

sum of a internal angles=50+50+50----> 150°  is not a triangle

therefore

That dimensions cannot create a triangle

case C. Three sides measuring 5 in,12 in,and 14 in

Applying the Triangle Inequality Theorem

5+12>14 -- >  is ok

14+5>12 --- > is ok

12+14>5 --- > is ok

That dimensions can create only one unique triangle

case  D. Three sides measuring 4 ft,8 ft, and 14 ft

Applying the Triangle Inequality Theorem

4+8>14 -- >  is not true

therefore

That dimensions cannot create a triangle

the answer is

Option C. Three sides measuring 5 in,12 in,and 14 in

The dimension that can create more than one triangle is; A: Three angles measuring 25, 65, and 90.

How to classify triangles?

It is pertinent to know that one of the basic properties of a triangle is that it's 3 Interior angles must sum up to 180°

Now, triangles could be classified under shape or by angles.

For example by angles, we have acute angle, and obtuse angle triangle while under shape, we have right angle triangle, scalene triangle e.t.c

Now,looking at the options, only option A fits the definition of a triangle because the sum of the 3 Interior angles are 180° and as such it can be classified under angles or sides which means more than one triangle can be created.

Hence, the dimension that can create more than one triangle is; A: Three angles measuring 25, 65, and 90.
