Worksheet: Hinge Theorem

In this worksheet, we will practice using the hinge theorem.

Q1:

Consider the following two triangles.

Length π‘Ž is congruent to 𝑑 and length 𝑏 is congruent to 𝑒 . Given that πœ™ is greater than πœƒ , what does the hinge theorem tell us about the lengths 𝑐 and 𝑓 ?

  • A 𝑓 and 𝑐 are equal.
  • B 𝑓 is less than 𝑐 .
  • C There is no relation between 𝑓 and 𝑐 .
  • D 𝑓 is greater than 𝑐 .

Q2:

Given that , use the hinge theorem to find the range of all possible values of in the figure.

  • A
  • B
  • C
  • D
  • E

Q3:

Consider triangles and in the figure.

Without completing any calculations, use the hinge theorem to determine whether is greater than, less than, or equal to .

  • A and are equal.
  • B is less than .
  • C is greater than .

Q4:

Given that 𝐢 𝐸 = 5 π‘₯ βˆ’ 1 1 and 𝐢 𝐡 = 9 , find the range of all possible values of π‘₯ using the Hinge theorem.

  • A 1 1 5 ≀ π‘₯ < 4
  • B 1 1 5 ≀ π‘₯ ≀ 4
  • C βˆ’ 1 1 5 ≀ π‘₯ ≀ 4
  • D 1 1 5 < π‘₯ < 4
  • E βˆ’ 1 1 5 < π‘₯ < 4

Q5:

In the figure, . Use the hinge theorem to find the range of all possible values of .

  • A
  • B
  • C
  • D
