Short Answer
Using the words from the word list, name all the parts of the isosceles triangle in the diagram below. Some words may be used more than once.
A diagram of a triangle, a corresponding word list, and answer spaces are shown.
· Triangle upper A upper C upper E is shown with segment upper A upper C and segment upper E upper C each labeled with the same tick mark.
· Upper B is located on upper A upper C.
· Upper D is located on upper E upper C.
· Upper F is located on upper A upper E.
· The word list contains vertex angle, base angle, leg, and base.
The answer spaces are:
· upper A large dash
· upper B large dash
· upper C large dash
· upper D large dash
· upper E large dash
· upper F large dash
(4 points)
The answer spaces are:
- Upper A: vertex angle, base angle
- Upper B: leg
- Upper C: vertex angle, base angle
- Upper D: leg
- Upper E: vertex angle, base angle
- Upper F: base
Answer:
The parts of the isosceles triangle in the diagram are:
· vertex angle: angle upper A
· base angle: angle upper C
· leg: upper B
· base: segment upper A upper C
The answer spaces are:
· upper A: vertex angle
· upper B: leg
· upper C: base angle
· upper D: (not mentioned in the question)
· upper E: base
· upper F: (not mentioned in the question)
To name all the parts of the isosceles triangle in the diagram, we can follow these steps:
1. Identify the vertices of the triangle: The diagram shows three vertices labeled upper A, upper B, and upper C.
2. Identify the sides of the triangle: The diagram shows several segments. We need to find the sides of the triangle. We can see that segment upper A upper C and segment upper E upper C are labeled with the same tick mark. Therefore, they are the equal sides of the isosceles triangle.
3. Identify the base of the triangle: The base of the isosceles triangle is the side that is not equal in length to the other two sides. In this case, it is segment upper E upper C.
4. Name the parts of the triangle:
- Vertex angle: The vertex angle is the angle formed at the vertex of the triangle. In this case, it is the angle at upper C.
- Base angle: The base angles are the angles formed at each end of the base. In this case, they are the angles at upper A and upper E.
- Leg: The leg is any of the two equal sides of the isosceles triangle. In this case, both segment upper A upper C and segment upper E upper C are the legs of the triangle.
- Base: The base is the side that is not equal in length to the other two sides. In this case, it is segment upper E upper C.
Now, let's fill in the answer spaces:
- upper A: leg
- upper B: leg
- upper C: vertex angle, base angle
- upper D: not present in the diagram, so we leave it blank
- upper E: leg, base angle
- upper F: not present in the diagram, so we leave it blank
