Answer:
2
Step-by-step explanation:
4g+4=2g+12
or , 4g-2g=12-4
or , 2g = 8
or, g=8/2
g= 2
Answer:
Step-by-step explanation:
The distance between two points is given by .
Here are the vertices of a triangle.
Longest side
Hence this is an acute triangle.
Answer:
You can prove that these triangles are congruent by SSS axiom.
Step-by-step explanation:
- The co-ordinates of points of triangle ABC are: A(-3,4), B(-4,1), C(0,3).
- Measure the length of every side of triangle ABC and DEF by using distance formula i.e. AB, BC, AC, DF, DE and EF.
- The co-ordinates of points of triangle DEF are: D(0,2), E(3,1), F(2,-2).
- By calculating the distance you can see that, BC=DF, AB=DE=AC=EF.
- Hence all three sides are equal that means the triangles are congruent by the SSS (side-side-side) axiom.
