Random 1

100

Whats a conditional statement?

A conditional statement is a logical statement that has two parts

200

Whats the "If-Then" Form?

The if-then form is when a conditional statement is written in the if-then form. The "if" part contains the hypothesis and the "then" part contains the conclusion

300

What does it mean to Converse a statement

To write the Converse of a conditional statement, you must exchange/ switch the hypothesis and the conclusion.

400

Whats the Inverse of a statement?

The Inverse of the statement is to negate both the hypothesis and the conclusion.

500

What is negation?

To negate both parts of the statement so that it is the opposite of the original

Random2

100

Whats a perpendicular line?

When two lines intersect to make a 90 degree right angle

200

Whats an equivalent statement?

When two statements are both true or both false

300

Whats the contra positive of a statement? 

To write the contrapositive of a conditional statement, first write the converse, then negate both the hypothesis

400

Whats the Base Angle Theorem for Isosceles Triangles? 

If two sides of a triangle are congruent, then the two sides opposite to them are congruent

500

Give me a example of the transitive POC

Look at example and see if its right

Random 3

100

Sketch out an isosceles triangle. Name the points A, B and C with B in the bottom left corner

What letter is the vertice?

 

B

200

Solve this (I will draw it for u) 

Alex look at 13 on 2.6 hmrk to give u the problem

y = 9

x = 4

300

Whats the Triangle Sum Theorem?

The sum of the interior angles of a triangle is 180 degrees

400

Whats the Reflexive POE

A thing equals itself

500

True or False? If two lines intersect then their intersection is exactly one point

True

Random 4

100

Draw a diagram of the Line- Intersection Postulate/ the If-Then as a diagram. 

If should look like an x with two lines intersecting

Then should look like the same thing but with a dot in the middle

200

Whats the Alternate Interior Angles Converse 

If two lines are cut by a transversal so the alternate angles are congruent, then the lines are parallel

300

Whats a bi-conditional statement?

When a conditional statement and its converse are both true, you can write them as a single bi-conditional statement. A bi-conditional statement is a statement that contains the phrase "if and only if"

400

True or False? Through any two points there exists more than one line. 

False

500

Solve: x+6=3x+10 

Then tell me which properties of equality you used. 

x = -2

Subtraction POE then Division POE

Random 5

100

Sketch out the diagram at the whiteboard I am pointing at. Copy it onto your own whiteboard. This is for safety reasons Antonio. Find angle 1, 2, 3, 4, and 5 and tell me what theorems you used. 

Angle 1 = 47 degrees

Angle 2 = 66 degrees

Angle 3 = 8 degrees

Angle 4 = 30 degrees

200

Whats the distance Formula

(x₂-x₁)² - (y₂-y₁)² 

300

Sketch a ray with start point A midpoint B and end point C. Prove AB is congruent to BC in a two column proof table

Look at it and see if its good

400

What kind of statement is this? "A line is a line perpendicular to a plane if and only if the line intersects the plane in a point and is perpendicular to every line in the plane that intersects it at that point"

Biconditional statement

500

3 TIMES THE AMOUNT OF POINTS SO 1500!! 

What is the saddest thing to ever happen in Mr Beast history

Coach Walls death 😭
