An isosceles triangle has angle a 30 degrees greater than angle b. In many cases, we will have to utilize the angle theorems we've seen to help us solve problems and proofs. Choose two given values, type them into the calculator and the remaining unknowns will be.
Side ac has a length of 6 mm and side ab has a length of 8 mm and angle bac is obtuse.
Triangle abc, shown below, has an area of 15 mm 2. Tick marks on an edge of a triangle are a common notation that reflects the length of the side, where the same number of ticks means equal length.
