What is the answer of this question

a) You have shown 3 pairs of corresponding sides, and no corresponding points. You could mark the upper left point on each figure, for example, as your corresponding points.

b) It is convenient to choose a dimension that is 1 unit in the smaller figure and find the corresponding measure in the larger one. You could use, for example, the lower left horizontal line segment, which is 1 unit long in the smaller figure and 4 units long in the larger figure. This ratio tells you ...

smaller/larger = 1/4

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
