First thing...put the numbers in order ...
9,10,11,12,12,13,14,15,15,16,17,18,18,19,20,22
Q1 (lower quartile) = 12
Q2 (median) = 15
Q3 (upper quartile) = 18
IQR = Q3 - Q1 = 18 - 12 = 6
range = (highest number - lowest number) = 22 - 9 = 13
Explanation:
If two triangles are congruent, this means they are the same shape and the same size.
By definition, all corresponding angles of two congruent triangles are congruent. Additionally, all corresponding sides of two congruent triangles are congruent.
When we know that two triangles are congruent and are showing that corresponding sides or corresponding angles of the triangles are congruent, we use the justification "CPCTC". This stands for:
<em>C</em><em>orresponding</em>
<em>P</em><em>arts of</em>
<em>C</em><em>ongruent</em>
<em>T</em><em>riangles are</em>
<em>C</em><em>ongruent</em>.
