BASIC MATH QUESTIONS WITH ACCURATE ANSWERS
When asked to round a place, only look at the digit next to the place.
Accurate Answer - Rounding
{3,4,5}
{5,12,13}
{8,15,17}
{7,24,25} Accurate Answer - 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.
Accurate Answer - 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. Accurate Answer - Similar Triangles
Angles= 45-45-90; sides= 1-1-√(2) Accurate Answer - Isosceles Right
Triangle
We get this by diving an equilateral triangle in half.
Has sides 1-√(3)-2. Accurate Answer - 30-60-90 triangle
The average of a group of consecutive integers is equal to the average of the
smallest and largest numbers. Accurate Answer - Average(Arithmetic
Mean) Tips
