For each set of angles or sides lengths, determine whether they could form a unique triangle, more than one triangle, or no triangle. 5 cm, 10 cm, 12 cm

8 ft, 12 ft, 20 ft

40°, 50°, 80°

28°, 51°, 101°​

They can form one triangle.

Step-by-step explanation: Since all triangle must have 180 degrees, there’s only one set of degrees that sum up to 180.

28+51+101=180

I’m sorry, but the feet/centimeters part you have to solve on your own. Remember, this is a learning community! No stress :) I can guarantee you won’t get it wrong though.

There’s many different triangles, and I’m sure from these feet/centimeters you can make at least one of the listed: Scalene (none of the sides are equal), isosceles (only 2 sides are equal) or equilateral triangle (all sides are equal). There’s also right triangles (which are triangles with one right angle also known as 90 degrees) that are either isosceles or scalene or both! Try your best and remember, no stress :)
