Enumerate the at least 3 types of Quadrilaterals.
Quadrilaterals are the polygons with 4 sides.
There are 6 Types:
1. Square
2. Rectangle
3. Rhombus
4. Parallelogram
5. Kite
6. Trapezoid
This Greek mathematician is credited with a theorem about right triangles that says the square of the hypotenuse equals the sum of the squares of the legs or expressed as: a2+b2=c2.
Pythagoras
It is the tendency of an object to resist changes in its motion.
Inertia

Tangent=opp/adj
Who created the Periodic Table of Elements?
Dmitri Mendeleev
He is known for formulating the periodic law and creating a version of periodic table of elements. The element 101 (Mendelevium) was named in his honor.
A chemical reaction that absorbs heat from its surroundings.
Endothermic Reaction
The type of cell division that produces four non-identical daughter cells.
Meiosis
Solve for the value of x:
4x−5=11
The answer to this problem is x=4.
Substitute 4 to x.
4x−5=11
transpose:
4x=11+5
4x=16
divide both side by 4:
x=4
checking:
4(4)-5=11
16-5=11
A ladder leans against a wall forming a right angle with the ground. Which side represents the hypotenuse?
The answer is ... Ladder
Wall-Opposite
Ground-Adjacent
Ladder-Hypotenuse
He is a mathematician known as the Father of Geometry and many of his theorems are still used today.
Euclid
What is the chemical formula of glucose?
C6H12O6
The layer of the Earth where tectonic plates float and move.
Asthenosphere
Two classes took a quiz.
Class A scores: 70, 75, 80, 85, 90
Class B scores: 50, 75, 80, 85, 110
Range
Class A: 90 − 70 = 20
Class B: 110 − 50 = 60
Identify which class performed better and why?
Range
Class A: 90 − 70 = 20
Class B: 110 − 50 = 60
Class A.
Smaller range means scores are more consistent, with no extremely low or unusually high outliers skewing results.
Each interior angle of an equilateral quadrilateral measures how many degrees?
90 degrees
The sum of interior angles of any quadrilaterals is equals to 360. Since it's equilateral, all sides are equal therefore all angles are also equal which means.
360 degrees /4 angles=90 degrees
What is the name of the scientist that proved lightning is electricity through his kite experiment?
Benjamin Franklin
He was known for his famous kite experiment to prove that clouds are electrified and that lightning is a form of electricity.
A runner covers 200m in 40s. What is the runner’s speed?
5m/s
Solution: 200m/40s = 5m/s
