Answer:
1. Reflect ABC about the line AC and then translate 1 unit to the right.
2. Translate ABC 1 unit to the right and then reflect it about the line AC.
Step-by-step explanation:
We are given that,
ABC is transformed using glide reflection to map onto DEF.
Since, we know,
'Glide Reflection' is the transformation involving translation and reflection.
So, we can see that,
ABC can be mapped onto DEF by any of the following glide reflections:
1. Reflect ABC about the line AC and then translate 1 unit to the right.
2. Translate ABC 1 unit to the right and then reflect it about the line AC.
Hence, any of the two glide reflection will map ABC onto DEF.
Answer:
Answer a: mST=20
Answer b: mST=48
Step-by-step explanation:
Problem a:
3a-5=2a+50
a=55
2(55)+50=160
180-160=20
Problem b:
180=4c-12
192=4c
48=c
Answer:
Step-by-step explanation:
Check if the lengths of the sides follows the Pythagorean theorem.
9² + 12² ≟ 15²
81 + 144 ≟ 225
225 = 225
Triangle ABC is a right triangle.
