Basic Math 43 Questions With Correct Answers
When asked to round a place, only look at the digit next to the place. - ️️Rounding {3,4,5} {5,12,13} {8,15,17} {7,24,25} - ️️Pythagorean Triplet If the sides given are larger, divide down by the greatest common factor. Do the computations in the smaller triangle and then scale back up. - ️️Right angled Triangle Similar figures have the same shape but different sizes. The angles in similar figures are always equal. We can prove two triangles are similar if they simply share two angles. Sides in similar figures are proportional. The scale factor k, is the factor by which all lengths in the smaller figure were multiplied to arrive at the lengths in the larger figure. If all the lengths are multiplied by k, then the area is multiplied by k squared, the scale factor squared. - ️️Similar Triangles Angles= 45-45-90; sides= 1-1-√(2) - ️️Isosceles Right Triangle We get this by diving an equilateral triangle in half. Has sides 1-√(3)-2. - ️️30-60-90 triangle
