Answer:
Given a square ABCD and an equilateral triangle DPC and given a chart with which Jim is using to prove that triangle APD is congruent to triangle BPC.
From the chart, it can be seen that Jim proved that two corresponding sides of both triangles are congruent and that the angle between those two sides for both triangles are also congruent.
Therefore, the justification to complete Jim's proof is "SAS postulate"
Step-by-step explanation:
Vertically opposite angles are equal
With this information we can form an equation
2x+14=60
Subtract 14 from both sides
2x=46
Divide both sides by 2
X=23
x = 23 degrees
Answer:
(0,-3)
(1,1)
(2,5)
Step-by-step explanation:
They're all correct. it doesn't matter which one you choose.
Answer: The answer is (C) 180° rotation.
Step-by-step explanation: Given that the point A maps to the point A' by a rotation. We are to select the statement that describes the rotation.
In the given figure, the co-ordinates of point A are (-3, 5) and after rotation, the co-ordinates of point A' are (3, -5).
Therefore, the point (x, y) changes to (-x, -y) after rotation. This is the result of 180° rotation.
Therefore, the point A is rotated through an angle of 180° to reach at the point A'.
Thus, the correct option is (C) 180° rotation.
Answer:
55
Step-by-step explanation:
Add 15+5+25+10 which is 55
