What parts of the circles are highlighted?
Blue=Semicircle
Pink=Diameter
100
What quadrilaterial is this?
Parallelogram

Can this statement be biconditional?
"If I attend Rosemont High, then I'm a high school student."
Not true; Not a biconditional statement.
If I'm a high school student, then I can attend ANY high school.
100
Where is the centroid located for each type of triangle?
The centroid is located on the interior for each triangle.
100
Who is the principal of Rosemont High?
Mr Jones

What can you say about <1 and <2?
<1 and <2 are vertical angles. Therefore, <1 and <2 are congruent.
200
What parts of a parallelogram are congruent always?
Opposite sides and Opposite angles
200
Find the highlighted angles.
Since this is an isosceles triangle, then the base angles are congruent. Then, <B=56.
Then, <A=68.
200
Definition of Incenter
Point of concurrency of the three angle bisectors of a triangle.

What is the name of Spider-Man from Earth 2099 in Into the Spider-Verse?
Miguel O'Hara
300
What's the relationship between an inscribed angle and its intercepted arc?
An inscribed angle is half the measure of its intercepted arc.
300
Which quadrilaterals have diagonals that bisect each other?
Parallelograms
Rectangles
Rhombus
Squares
300
Find the missing angles.
<ECD = 70
<CED = 65
300
How do you find the centroid?
Create three medians (line segment from a triangle's vertex to the midpoint of the opposite side) within a triangle. The point of concurrency for the medians is the centroid.

True or False:
The Old Sacramento paths we walk on and use now are the second floor of Old Sac.
TRUE!
To reduce flood damage, the people of Old Sac raised everything by one floor.
Fun Fact: There's underground passageways as far the Capital.
400
If an arc is 90 degrees, how many degrees is the inscribed angle that intercepts it?
The inscribed angle is 45 degrees.
400
True or False:
A square is a rhombus.
True!
A rhombus needs all equal sides, diagonals that bisect each other, and opposite congruent angles.
400
Is it possible for a triangle to be made up of these side lengths:
10, 13, 2
No!
Triangle Inequality Theorem.
10 + 2 is not greater than 13
400
What constructs do you need to draw an inscribed circle?
-Use angle bisectors to find the incenter of a triangle
-Use the incenter as the center of our inscribed circle
-Radius of inscribed circle is perpendicular to the side of the triangle.

What year was Rosemont High built? (~5 year range)
2003
(1998 - 2008)
500
What are all the congruent angle pairs you see?
500
Noah drew a quadrilateral with two pairs of adjacent congruent sides. What are the possible specific quadrilaterals that Noah could have drawn?
(Hint: There's three possible answers)
Square, rhombus, and kite
500
The range for our third side in this triangle is 3<AC<19.
If we find out <B is the smallest angle, how does this change our range?
Since <B is the smallest angle, then the side opposite that angle is the smallest. So, AC is the smallest side. Therefore, 3<AC<8
500
If A is a vertex of our triangle,
B is the midpoint of the opposite side of the vertex A,
AB is a median with C as the centroid of our triangle.
Is the length of CB double the length AC OR is AC double CB?
AC would be double CB
