Answer:
I had to repost my answer because i got deleted from some reason
Step-by-step explanation:
I first plotted the three points and from from their position it was clear which pairs to join to start a rectangle.
At this point you need to check to make sure the angle at B is a right angle. Find the slope of the line segments AB and BC and check that the product of the slopes is -1.
From the diagram you can now see where the fourth point D has to be. If AB and CD are parallel then D must be 3 units to the left of C and 2 units above C. Find the coordinates of D and then check by finding the slopes of CD and DA and showing that the angle at D is a right angle.
I hope this helps
The answer is B. 0.25 inch. Lets multiply all of them by the same factor. Since A. and B. have 3 decimals, lets divide all numbers by 1000: A. 0.026 * 1000 = 26, B. 0.25 * 1000 = 250, C. 0.24 * 1000 = 240, D. 0.025 * 1000 = 25. So, by comparing the whole numbers, it can be concluded that the biggest steel rod is B. 0.25 inch.
The sides of a real triangle satisfy the <em>triangle inequality</em>, which just says any two sides add up to more than the third. It's strictly more; if two sides add up to exactly the third that's called a <em>degenerate triangle</em>. It's not a real triangle because the vertices are three collinear points.
The triangle equality fails when the sum of the two smallest sides fails to exceed the the largest side.
A. 4+6=10, degenerate triangle, not a real triangle
B. 4+7>7, isosceles triangles are real, SELECT
C. 4+3<10, not a real triangle
D. 4+7=11, degenerate triangle again
