Question:
Use Figure 1
PH = 5,PT = 10, and
HT = 7, give the angles of
triangle PTH in order from least
to greatest
Answer:
m<PTH < m<P < m<PHT
Question: Use figure 1
If m<P = 40 and m<PTH = 30,
order the sides of triangle PTH
from greatest to least
Answer: PT > HT > PH
Question: Using figure 1
If PH is perpendicular to HT, what is
the longest side of triangle PHT?
Answer: PT
Question:Use figure 1
m<P=50 m<PHT = 90 m<PTH = 40
m<THA = 60 m<A = 90 m<HTA = 30
Find the longest side of the entire shape.
Answer: PT
Question: Use figure 1
If PT = AT and
m<PTH < m<HTA,
what inequality statement can you
state using the Hinge Theorem?
Answer: PH < HA
Question: Can you form a
triangle given the side
lengths of 5, 8, 14? Explain
why or why not.
Answer:
NO – 5 + 8 < 14
Given that two sides of a triangle
are 15 and 4, give all possible
values for the third side.
Answer:
