Kristina wants to prove that the base angles of any isosceles triangle are congruent. She
draws ADEF, as shown, and then draws segment EG, the angle bisector of E.
Use the drop-down menus below to complete Kristina's proof that base angles of an
isosceles triangles are congruent.
CLEAR
CHECK
Step 1: _DEG and ZFEG are
congruent
by definition of an angle bisector.
Step 2: It is given that segment DE 2 segment EF, and segment EG-segment EG by
the reflexive property.
Step 3: ADEG = AFEG by
Conclusion: So, 2D : _F because they are corresponding parts of congruent
triangles.

Find the area and perimeter of each composite figure. use 3.14 for π. round your answer to the nearest tenth. a square and a right triangle share a common side. image long description a 3-meter by 0.5-meter rectangle has triangles attached like wings to the 3-meter sides. the other two sides of both triangles measure 2.5 meters. the height of each triangle is 2 meters. a 6-inch by 4-inch rectangle has 2 half-circles attached like wings to the 6-inch sides. the radius of each half-circle is 3 inches. find the surface area and volume of each figure. use 3.14 for π. round your answer to the nearest tenth. a right circular cylinder has a base radius of 6 yards and a height of 20 yards. a rectangular prism has a base that is 9 centimeters long and 7 centimeters wide. the height is 2 centimeters. a rectangular prism has a base that measures 11 millimeters by 11 millimeters. the height is 11 millimeters.

Television sizes are based on the length of the diagonal of the television's rectangular screen. so, for example, a 70-inch television is a television having a diagonal screen length of 70 inches. if a 70 inch television's diagonal forms a 29°angle with the base of the screen, what is the vertical height (1) of the screen to the nearest inch? 70 inhin
