1 Three dimensions The distance between point and plane Distance between point and plane is vertical line which connects point and center pointof plane. ( jarak titik ke bidang adalah panjang garis tegak lurus dari titik ke bidang ) A A’

2 A cube ABCD.EFGH with edge 6 cm, find the distance between point A to plane BCGF A B CD H G E F The distance between point A and plane BCGF is line AB = 6 cm

3 AB DC E F H G A cube ABCD.EFGH with edge 6 cm, find the distance between point C to plane BDG C’ O The distance between C to plane BDG is CC’ OC = (OG) 2 = (OC) 2 + (CG) 2 = = 54 See the triangle OCG The area OCG =
