Can someone help with number 4 please? Due in 15 mins!!
quester [9]

Answer:

A. AG = 2 × GD

F. GE = (1/2) × BG

Step-by-step explanation:

The given point <em>G</em> on triangle ΔABC, which is the point of intersection of the medians of the triangle, is the centroid of the triangle

The centroid divides each median line in the ratio 2:1, therefore, we have;

The length of AG = 2 × GD, CG = 2 × GF, and BG = 2 × GE

∴ GE = (1/2) × BG

Therefore, the correct options are;

A. AG = 2 × GD, and F. GE = (1/2) × BG

Identify the property that justifies the statement.<br><br> ∠XYZ≅∠PDQ and ∠PDQ≅∠ABC, so ∠XYZ≅∠ABC.
MArishka [77]

Answer: Transitive property of Equality.

Therefore if ∠XYZ≅∠PDQ and ∠PDQ≅∠ABC then by transitive property of equality we have ∠XYZ≅∠ABC.

The law of transitivity tells that if a equals to b and b equals to c then a equals to c.

For example If Jane has same height of Susan and Susan has same height of Tina then Jane has same height of Tina.
