Examine the two angle bisector constructions.
example a: a construction of angle abc. there is an arc drawn from the vertex b that creates points a and c. the points are the same distance from the vertex. point d has been created from intersecting arcs that are the same distance from points a and c. a line has been drawn from point b through point d.
example b: a construction of angle abc. there is an arc drawn from the vertex b that creates point a. another arc from the vertex b creates point c. points a and c are not the same distance from point b. point d has been created from intersecting arcs constructed from points a and c. a line has been drawn from point b through point d.
1. which angle bisector was created by following the construction steps correctly? how do you know?
2. which angle bisector was constructed incorrectly? explain the step that was completed incorrectly.
3. two students created a list of steps for the following construction. which student has steps in the correct order, and which does not? explain.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

sorry can't

i googled though and something came up but it was in science langueage not common english sooo
