TSIA2 Study Guides: Math 2023/ 34
Questions and Answers/ Verified.
Real Numbers - -All numbers that are on number line. Integers plus fractions, decimals,
and irrationals
-Slope of the line - -(𝑦2−𝑦1)/(𝑥2-𝑥1)=𝑟𝑖𝑠𝑒/𝑟𝑢𝑛
-Point-slope form - -y-y1=m(x-x1), where (x1,y1) is any point on the line and m is the
slope of the line
-Slope-intercept form - -y=mx+b, where m is the slope and b is the y-intercept of the
line.
-Pythagorean Theorem: - -a²+b²=c²
-Area of a triangles - -A=1/2bh
-The angles inside a triangle add up to ? - -180 degrees
-equilateral triangle - -These triangles have three equal sides, and all three angles are
60∘
-Isosceles - -An isosceles triangle has two equal sides. The "base" angles (the ones
opposite the two sides) are equal (see the 45∘ triangle above).
-Area of a Circle - -A=π𝑟2
-Circumference of a Circle - -C =2π𝑟
